November 17 | ��(Honors)
Growing concerns about the health of America’s 250-year experiment in representative democracy should prompt us to think deeply about how civic belonging has been defined in U.S. society since the nation’s founding and what current efforts to restrict access and opportunities for civic participation mean for our collective futures. Civic Belonging in an Anti-Democratic Age brings together UW faculty whose teaching and research straddle law, politics, human rights, urban studies, and digital technologies for a lively interdisciplinary conversation about the stakes of belonging in U.S. society. Join us as we examine the current moment and ask how we can work towards a more inclusive democratic future. Free.

November 17 | (Simpson Center for the Humanities)
We humanists are hoping for, and many of us are fighting for, a new day in the United States when the production and circulation of knowledge are understood as keystones of democracy and of human thriving – and thus as deserving of substantial public investment. Having worked so long in the spirit of doing a lot with a little, how do we envision the humanities in conditions of abundance? What shifts in traditional academic culture and policy will help us meet those conditions? In the spirit of Octavia Butler’s future-oriented thinking, this talk draws together many threads of contemporary thinking to sketch a future where American universities center the values and practices of liberal arts-grounded humanistic inquiry. Free.

In this talk, Joanne Leow traces the process of writing and publishing her hybrid memoir Exhumations: In the Body of a Petrostate. By following the trajectory that her writing took from online writing to print journal to bound book, she considers what it means to publish work about Singapore while in the diaspora. Exhumations oscillates between socio-political and cultural analysis and a memoir of grief and illness. Seeing our porous bodies as part of a contaminated and compromised system based on extraction, violence, and political repression, her work asks what must be made visible in our current moment. In doing so, she draws from her time as a journalist for state media, her positionality as a “quitter,” and her current work as a scholar based in Canada. These intersecting experiences have allowed her to explore histories of activism, censorship, weapons manufacturing, terraforming, and petroleum refining in Singapore. Free.

November 19 | (Henry Art Gallery)
Artist Trenton Doyle Hancock discusses his varied career and current projects. Inspired by the world-building of comics, Hancock’s work iterates over time through the investigation of character, story, and symbols.

November 19 | (Jackson School of International Studies)
This talk examines the historical political divergence between China and Europe. While both regions experienced repeated shifts in territorial unification, political stability, and institutional development in earlier periods, from the medieval period onward, their trajectories increasingly diverged. Europe gradually evolved toward a polycentric political order, while China consolidated into a centralized and authoritarian state. This talk proposes the development of China’s imperial civil service examination system as a key driver of this divergence. Drawing on a synthesis of several recent works, it approaches the question from three complementary perspectives: macro-level patterns of political development, micro-level quantitative evidence on bureaucratic recruitment, and formal theories of political equilibrium and institutional change. Free.

November 20 | (Classics)
Eight years after demonstrators in Charlottesville, Virginia, chanted “Jews will not replace us!” at a rally whose promotional poster featured the acronym SPQR and where one group of activists carried shields emblazoned with images of the Roman fasces, most Classical scholars are aware that white nationalists and other hateful actors take inspiration from Greco-Roman antiquity. There is less consensus, however, about what this phenomenon means for those of us who research and teach about the ancient Greco-Roman world. In this lecture, Curtis Dozier, author of The White Pedestal: How White Nationalists Use Ancient Greece and Rome to Justify Hate (Yale University Press, 2026), draws on his ten years’ experience documenting appropriations of Greco-Roman antiquity by hate groups to bring into focus what white nationalist classicism reveals about the material we study, our discipline, our nation, and ourselves. Free.

November 19 – 21 | (Meany Center for the Performing Arts)
Taiwan’s Hung Dance makes its Seattle debut with BIRDY, a powerful and poetic work choreographed by the company’s founder and artistic director Lai Hung-Chung. Performed by eight dancers, the piece blends contemporary dance with elements of Chinese opera, Tai Chi and myth. Using striking props like rattan poles and flowing pheasant feathers (Ling Zi), BIRDY explores the tension between freedom and constraint, personal feeling and social pressure. The movement is bold, fluid and deeply human. BIRDY invites audiences to reflect on the desire to break free, and the quiet strength it takes to keep moving within the world around us.

A ������˾��-led center for optoelectronics — technologies that combine light and electronics — brings researchers from 14 universities across the U.S. together with the mission to develop new materials to transform information technology with light. This research has broad ranging applications, from enabling photorealistic virtual reality displays for telehealth calls, to secure, optical quantum communication links to ensure that data remains private on the internet.

Founded in 2021 as a , the , or NSF IMOD, has received a second round of funding from the NSF to continue its work for the next five years.

The research tackled by NSF IMOD is so interdisciplinary that it requires researchers from backgrounds such as chemistry, physics, engineering and materials science to work together.

“There’s still this idea that scientists go in their labs, put on their safety goggles and lab coats, and then work alone for hours at a time. The point of this center is to tackle problems that are too big for one scientist or even two or three to tackle by themselves,” said NSF IMOD director , UW professor of chemistry. “We have all these people from different disciplines working together to advance optoelectronics and semiconductor technology that we couldn’t do just as individual scientists.”

“Until our center came along, quantum dots were thought of as something you made in a beaker in a chemistry lab. And if you could paint them on a TV or phone display, that was great,” said Ginger, who is also the B. Seymour Rabinovitch Endowed Chair in Chemistry and the chief scientist at the UW . “But they weren’t something that you could put as a discrete component in an optoelectronic circuit. That’s something that we’ve proven you can do.”

With chemists, material scientists, mechanical engineers, chemical engineers, physicists and electrical engineers on the team, researchers at NSF IMOD created something unprecedented: a way to print quantum dots, . The team showed that they could strategically place quantum dots into specific cavities, which could one day be the building blocks for quantum communication, and possibly even quantum computing.

The team hopes to continue this research direction over the next five years, further refining quantum dots as well as the cavities the dots get placed into.

NSF IMOD’s interdisciplinary nature gets passed down to its students as well. One of the center’s main goals is to develop researchers into leaders in the fields of semiconductor and optoelectronic technology. Every summer, NSF IMOD trainees from different disciplines come together at the UW for in multiple disciplines. The students synthesize quantum dots, study single photons of light in UW’s , make quantum dots, and learn to calculate the electronic structures of advanced materials. The collaborations established during this course and throughout the NSF IMOD training program helps students graduate with the ability to work in complex, interdisciplinary teams.

Trainees also gain real-world experience in the form of internships at a variety of companies, including some of NSF IMOD’s industry and national lab partners. A partial list of NSF IMOD’s partners includes ; ; ; ; ; and More partner information can be found on .

“We’re already seeing our students get hired at everything from startup companies to large semiconductor firms for the exact skills they’re being trained for in the center,” Ginger said. “We’re really excited to see our students start taking important roles, and then eventually we hope they move into leadership roles in this space of commercializing new semiconductor materials.”

And it’s not just graduate students who benefit from NSF IMOD. The center hosts a program, and has programming for younger students as well. As part of their science communication training, NSF IMOD trainees become who can facilitate outreach events, such as at the Pacific Science Center. The team has also developed a for K-12 teachers to find lesson plans to use in their own classrooms.

“Just as the atomic structure of a quantum dot produces unique and exciting properties, the exceptionally interdisciplinary structure of NSF IMOD is enabling foundational science and technological innovations that would not otherwise be possible,” said , a program director in the NSF Directorate for Mathematical and Physical Sciences, which manages NSF IMOD.

Over the past five years, NSF IMOD has published 140 papers, hosted 36 undergraduate students through its REU program and hosted more than 85 outreach events.

“One day I hope that we’ll have photonic computing where we’re massively reducing the energy cost for computation by using a computing paradigm that’s based on the research we’re doing now,” Ginger said. “That’s the kind of thing that’s probably still a decade or more away. But that’s why the government invests in basic science now, because the basic science research of the materials today leads to technology that exists 15 years from now.”

NSF is expected to provide NSF IMOD $22 million over the five-year term of the award. The 14 academic institutions that make up NSF IMOD are the ������˾��; University of California, Berkeley; Columbia University; University of Chicago; Northwestern University; University of Pennsylvania; University of Maryland; Georgia Institute of Technology; University of Colorado Boulder; Arizona State University; Rice University; Lehigh University; City College of New York; and University of Maryland, Baltimore County.

In addition to Ginger, other UW faculty involved with NSF IMOD include , associate professor of physics and of electrical and computer engineering at the UW; , a UW professor of chemistry; , professor of electrical and computer engineering; , associate professor of mechanical engineering and of materials science and engineering, and technical director of the Washington Clean Energy Testbeds; and , professor of physics and of electrical and computer engineering.

The ad – entitled “” – will air alongside the fan-favorite “” spot. The new spot focuses on how the ������˾�� and other Big Ten universities make America healthier, safer and more prosperous in a variety of ways, from discovering new medical treatments to developing healthier foods to driving economic growth.

“The ������˾�� is proud to join our Big Ten peers in showcasing the power of education, research and innovation through this collaborative campaign. Leveraging one of the most visible stages in college sports, these ads highlight to a broad audience how student-athlete competition unites people, while also amplifying the value of each Conference university’s impact,” said ������˾�� President Robert J. Jones, who was previously chair of the Big Ten Council of Presidents and Chancellors and, along with President Emerita Ana Mari Cauce, was a champion of the project.

“Through our Big Ten membership, the UW gains visibility for its role—locally, nationally and beyond—in driving progress and fostering stronger communities nationwide,” Jones said.

Collectively, the 18 members of the Big Ten Conference educate more than 817,000 students and conduct $19.6 billion in research each year. The vast majority of that research is conducted thanks to the American people and their support for federal investments in the nation’s global leadership in health and innovation.

“The Big Ten Conference is an association of 18 world-class universities sharing a common mission of research, teaching and public service, alongside shared practices and policies that reinforce the priority of academics in the lives of its student-athletes,” said Big Ten Commissioner Tony Petitti. “We look forward to highlighting the impact our member institutions make every day in their communities and across the nation.”

“We Are Here” will air on linear and digital platforms during sporting events featuring Big Ten universities, utilizing airtime allocated to the Conference as part of its media agreements, including the Big Ten Network (BTN). From concept to completion, Valentina Gomez Bravo, executive creative director in (UMAC), led a multidisciplinary team of creative staff from Big Ten member universities in developing the ad under the auspices of the .

This new initiative builds on other Conference efforts, including research vignettes highlighting the impact of university research that air during select BTN sporting event broadcasts. That included vignettes about the UW last season featuring the and .

“We Are Here” is the first in a planned series of three ads, which over the course of the series will feature footage from all 18 universities.

“Our digital technology operates through a series of electronic on-off switches that control the flow of current and voltage,” said , a research scientist at the ������˾��. “But our bodies operate on chemistry. In our brains, neurons propagate signals electrochemically, by moving ions — charged atoms or molecules — not electrons.”

Implantable devices from pacemakers to glucose monitors rely on components that can speak both languages and bridge that gap. Among those components are OECTs — or organic electrochemical transistors — which allow current to flow in devices like implantable biosensors. But scientists long knew about a quirk of OECTs that no one could explain: When an OECT is switched on, there is a lag before current reaches the desired operational level. When switched off, there is no lag. Current drops almost immediately.

A UW-led study has solved this lagging mystery, and in the process paved the way to custom-tailored OECTs for a growing list of applications in biosensing, brain-inspired computation and beyond.

“How fast you can switch a transistor is important for almost any application,” said project leader , a UW professor of chemistry, chief scientist at the UW Clean Energy Institute and faculty member in the UW Molecular Engineering and Sciences Institute. “Scientists have recognized the unusual switching behavior of OECTs, but we never knew its cause – until now.”

In a published April 17 in Nature Materials, Ginger’s team at the UW — along with Professor at the Okinawa Institute of Science and Technology in Japan and Professor at Zhejiang University in China — report that OECTs turn on via a two-step process, which causes the lag. But they appear to turn off through a simpler one-step process.

In principle, OECTs operate like transistors in electronics: When switched on, they allow the flow of electrical current. When switched off, they block it. But OECTs operate by coupling the flow of ions with the flow of electrons, which makes them interesting routes for interfacing with chemistry and biology.

The new study illuminates the two steps OECTs go through when switched on. First, a wavefront of ions races across the transistor. Then, more charge-bearing particles invade the transistor’s flexible structure, causing it to swell slightly and bringing current up to operational levels. In contrast, the team discovered that deactivation is a one-step process: Levels of charged chemicals simply drop uniformly across the transistor, quickly interrupting the flow of current.

Knowing the lag’s cause should help scientists design new generations of OECTs for a wider set of applications.

“There’s always been this drive in technology development to make components faster, more reliable and more efficient,” Ginger said. “Yet, the ‘rules’ for how OECTs behave haven’t been well understood. A driving force in this work is to learn them and apply them to future research and development efforts.”

Whether they reside within devices to measure blood glucose or brain activity, OECTs are largely made up of flexible, organic semiconducting polymers — repeating units of complex, carbon-rich compounds — and operate immersed in liquids containing salts and other chemicals. For this project, the team studied OECTs that change color in response to electrical charge. The polymer materials were synthesized by Luscombe’s team at the Okinawa Institute of Science and Technology and Li’s at Zhejiang University, and then fabricated into transistors by UW doctoral students Jiajie Guo and Shinya “Emerson” Chen, who are co-lead authors on the paper.

“A challenge in the materials design for OECTs lies in creating a substance that facilitates effective ion transport and retains electronic conductivity,” said Luscombe, who is also a UW affiliate professor of chemistry and of materials science and engineering. “The ion transport requires a flexible material, whereas ensuring high electronic conductivity typically necessitates a more rigid structure, posing a dilemma in the development of such materials.”

Guo and Chen observed under a microscope — and recorded with a smartphone camera — precisely what happens when the custom-built OECTs are switched on and off. It showed clearly that a two-step chemical process lies at the heart of the OECT activation lag.

Past research, including by Ginger’s group at the UW, demonstrated that polymer structure, especially its flexibility, is important to how OECTs function. These devices operate in fluid-filled environments containing chemical salts and other biological compounds, which are more bulky compared to the electronic underpinnings of our digital devices.

The new study goes further by more directly linking OECT structure and performance. The team found that the degree of activation lag should vary based on what material the OECT is made of, such as whether its polymers are more ordered or more randomly arranged, according to Giridharagopal. Future research could explore how to reduce or lengthen the lag times, which for OECTs in the current study were fractions of a second.

“Depending on the type of device you’re trying to build, you could tailor composition, fluid, salts, charge carriers and other parameters to suit your needs,” said Giridharagopal.

OECTs aren’t just used in biosensing. They are also used to study nerve impulses in muscles, as well as forms of computing to create artificial neural networks and understand how our brains store and retrieve information. These widely divergent applications necessitate building new generations of OECTs with specialized features, including ramp-up and ramp-down times, according to Ginger.

“Now that we’re learning the steps needed to realize those applications, development can really accelerate,” said Ginger.

Guo is now a postdoctoral researcher at the Lawrence Berkeley National Laboratory and Chen is now a scientist at Analog Devices. Other co-authors on the paper are , a former UW postdoctoral researcher in chemistry who is now an assistant professor at the University of Utah; Jonathan Onorato, a UW doctoral alum and scientist at Exponent; and Kangrong Yan and Ziqui Shen of Zhejiang University. The research was funded by the U.S. National Science Foundation, and polymers developed at Zhejiang University were funded by the National Science Foundation of China.

In an experiment akin to stop-motion photography, an international team of scientists has isolated the energetic movement of an electron in a sample of liquid water — while “freezing” the motion of the much larger atom it orbits.

The finding reveals the immediate response of an electron when hit with an X-ray, an essential step in understanding the effects of radiation exposure on objects and people. The results, Feb. 15 in the journal Science, provide a new window into the electronic structure of molecules in the liquid phase on a timescale previously unattainable with X-rays.

“What happens to an atom when it is struck by ionizing radiation, like an X-ray? Seeing the earliest stages of this process has long been a missing piece in understanding how radiation affects matter,” said co-senior author , the Larry R. Dalton Endowed Chair in Chemistry at the ������˾�� and a laboratory fellow at the Pacific Northwest National Laboratory. “This new technique for the first time shows us that missing piece and opens the door to seeing the steps where so much complex — and interesting — chemistry occurs!”

Li co-led the team behind this breakthrough with co-senior authors , a distinguished fellow at Argonne National Laboratory and professor at the University of Chicago, and , professor at the German Electron Synchrotron and the University of Hamburg. The team received critical funding and support from the , a Department of Energy center headquartered at PNNL.

The collaboration used a combination of experiments and theoretical insights to see in real time what happens when ionizing radiation from an X-ray source hits matter. Revealing these moments is not as simple as snapping a photo. Subatomic particles move so fast that capturing their actions requires using a probe that can measure time in attoseconds. There are more attoseconds in a second than there have been seconds in the history of the universe.

“Until now radiation chemists could only resolve events at the picosecond timescale, a million times slower than an attosecond,” said Young. “It’s kind of like saying ‘I was born and then I died.’ You’d like to know what happens in between. That’s what we are now able to do.”

The team — under the guidance of Young and co-lead author , a postdoctoral researcher at Argonne — set out to develop a whole new experimental approach to achieve attosecond resolution using X-rays. Attosecond X-ray pulses are only available in a handful of specialized facilities worldwide, so the team partnered with scientists at the in California to use the facility’s Linac Coherent Light Source for developing attosecond X-ray free-electron lasers, with key input from scientists at PNNL.

The resulting technique, AX-ATAS — or all X-ray attosecond transient absorption spectroscopy — employed two delicate X-ray pulses: One to “excite” its target matter and one to probe how the excited matter responded. This approach would theoretically allow the scientists to “watch” electrons energized by X-rays as they move into an excited state, all before the bulkier atomic nucleus has time to move. They chose the liquid water as their test case for an experiment.

“And on our first experiment, it worked!” said Li. “But the signal we picked up in the data was ‘convoluted.’ It turns out that, in this transient snapshot, we were probing so many quantum states that we had to develop a completely new computational analysis method to understand the data.”

Quantum mechanical principles underlie the behavior of all matter, but its signatures are often hidden in experiments like these. But, using AX-ATAS at the attosecond timescale, the scientists were picking up quantum-level details — and needed new methods to make sense of the data.

To that end, Li, a theoretical chemist, worked with co-lead author Lixin Lu — who conducted this research as a UW doctoral student in chemistry and is now a postdoctoral researcher at Stanford University — to reproduce the signals observed at SLAC. The German Electron Synchrotron-based team under Santra and co-lead author Swarnendu Bhattacharyya, a postdoctoral researcher, modelled the liquid water response to attosecond X-rays to verify that the observed signal was indeed confined to the attosecond timescale.

“Using the Hyak supercomputer at the ������˾��, we developed a cutting-edge computational chemistry technique that enabled detailed characterization of the transient high-energy quantum states in water,” said Li, who is also UW Associate Vice Provost for research cyberinfrastructure and member faculty at the UW Clean Energy Institute. “This methodological breakthrough yielded a pivotal advancement in the quantum-level understanding of ultrafast chemical transformation, with exceptional accuracy and atomic-level detail.”

The team’s analysis resolved a long-standing scientific debate about whether X-ray signals seen in previous experiments are the result of hydrogen atom dynamics or different structural “motifs” of water. The experiments showed no evidence for two structural motifs in ambient liquid water.

“Basically, what people were seeing in previous experiments was the blur caused by moving hydrogen atoms,” said Young. “We were able to eliminate that movement by doing all of our recording before the atoms had time to move.”

The current investigation builds upon the new science of attosecond physics, . Working at the attosecond timescale will allow the researchers to understand complex radiation-induced chemistry at a fundamental level. This team initially came together to develop tools to understand the effect of prolonged exposure to ionizing radiation on the chemicals found in nuclear waste.

The researchers envision the current study as the beginning of a whole new direction for attosecond science.

“The methodology we developed permits the study of the origin and evolution of reactive species produced by radiation-induced processes, such as encountered in space travel, cancer treatments, nuclear reactors and legacy waste,” said Young.

Researchers led by , a ������˾�� associate professor of physics and Clean Energy Institute researcher, and Philip Ryan, a physicist at the U.S. Department of Energy’s Argonne National Laboratory, have made a discovery that could enable this more efficient future. In a published Nov. 24 in Science Advances, the team reports finding a superconducting material that is uniquely sensitive to outside stimuli, enabling the superconducting properties to be enhanced or suppressed at will. This discovery could enable new opportunities for switchable, energy-efficient superconducting circuits.

Superconductivity is a mechanical phase of matter in which an electrical current can flow through a material with zero resistance. This leads to perfect electronic transport efficiency. Superconductors are used in the most powerful electromagnets for advanced technologies such as magnetic resonance imaging, particle accelerators, fusion reactors and even . Superconductors are also used in quantum computing.

Today’s electronics use semiconducting transistors to switch electric currents on and off quickly, creating the binary ones and zeroes used in information processing. Since these currents must flow through materials with finite electrical resistance, some of the energy is wasted as heat. This is why your computer heats up over time. The low temperatures needed for superconductivity — usually more than 200 degrees Fahrenheit below freezing — makes those materials impractical for hand-held devices. However, they could conceivably be useful on an industrial scale.

The research team, under the direction of — then a UW doctoral student in physics and a fellow at the UW Clean Energy Institute — examined an unusual superconducting material with exceptional tunability. This crystal is made of flat sheets of ferromagnetic europium atoms sandwiched between superconducting layers of iron, cobalt and arsenic atoms. Finding ferromagnetism and superconductivity together in nature is extremely rare, according to Sanchez, as one phase usually overpowers the other.

“It is actually a very uncomfortable situation for the superconducting layers, as they are pierced by the magnetic fields from the surrounding europium atoms,” said Sanchez, who is now a postdoctoral researcher at the Massachusetts Institute of Technology. “This weakens the superconductivity and results in a finite electrical resistance.”

To understand the interaction of these phases, Sanchez spent a year as a resident at one of the nation’s leading , the Advanced Photon Source, a DOE Office of Science user facility at Argonne. Working with physicists at the APS, Sanchez developed a comprehensive characterization platform capable of probing microscopic details of complex materials.

Using a combination of X-ray techniques, Sanchez and his collaborators showed that applying a magnetic field to the crystal can reorient the europium magnetic field lines to run parallel to the superconducting layers. This removes their antagonistic effects and allows a zero-resistance state to emerge. Using electrical measurements and X-ray scattering techniques, the researchers confirmed that they could control the behavior of the material.

“The nature of independent parameters controlling superconductivity is quite fascinating, as one could map out a complete method of controlling this effect,” said Ryan. “This potential posits several fascinating ideas including the ability to regulate field sensitivity for quantum devices.”

The team then applied stresses to the crystal with interesting results. They found the superconductivity could be either boosted enough to overcome the magnetism — even without re-orienting the field — or weakened enough that the magnetic reorientation could no longer produce the zero-resistance state. This additional parameter allows for the material’s sensitivity to magnetism to be controlled and customized.

“This material is exciting because you have a close competition between multiple phases, and by applying a small stress or magnetic field, you can boost one phase over the other to turn the superconductivity on and off,” said Sanchez. “The vast majority of superconductors aren’t nearly as easily switchable.”

For decades, scientists have been probing the potential of two-dimensional materials to transform our world. 2D materials are only a single layer of atoms thick. Within them, subatomic particles like electrons can only move in two dimensions. This simple restriction can trigger unusual electron behavior, imbuing the materials with “exotic” properties like bizarre forms of magnetism, superconductivity and other collective behaviors among electrons — all of which could be useful in computing, communication, energy and other fields.

But researchers have generally assumed that these exotic 2D properties exist only in single-layer sheets, or short stacks. The so-called “bulk” versions of these materials — with their more complex 3D atomic structures — should behave differently.

Or so they thought.

In a published July 19 in Nature, a team led by researchers at the ������˾�� reports that it is possible to imbue graphite — the bulk, 3D material found in No. 2 pencils — with physical properties similar to graphite’s 2D counterpart, graphene. Not only was this breakthrough unexpected, the team also believes its approach could be used to test whether similar types of bulk materials can also take on 2D-like properties. If so, 2D sheets won’t be the only source for scientists to fuel technological revolutions. Bulk, 3D materials could be just as useful.

“Stacking single layer on single layer — or two layers on two layers — has been the focus for unlocking new physics in 2D materials for several years now. In these experimental approaches, that’s where many interesting properties emerge,” said senior author , a UW assistant professor of physics and of materials science and engineering. “But what happens if you keep adding layers? Eventually it has to stop, right? That’s what intuition suggests. But in this case, intuition is wrong. It’s possible to mix 2D properties into 3D materials.”

The team, which also includes researchers at Osaka University and the National Institute for Materials Science in Japan, adapted an approach commonly used to probe and manipulate the properties of 2D materials: stacking 2D sheets together at a small twist angle. Yankowitz and his colleagues placed a single layer of graphene on top of a thin, bulk graphite crystal, and then introduced a twist angle of around 1 degree between graphite and graphene. They detected novel and unexpected electrical properties not just at the twisted interface, but deep in the bulk graphite as well.

The twist angle is critical to generating these properties, said Yankowitz, who is also a faculty member in the UW Clean Energy Institute and the UW Institute for Nano-Engineered Systems. A twist angle between 2D sheets, like two sheets of graphene, creates what’s called a moiré pattern, which alters the flow of charged particles like electrons and induces exotic properties in the material.

In the UW-led experiments with graphite and graphene, the twist angle also induced a moiré pattern, with surprising results. Even though only a single sheet of graphene atop the bulk crystal was twisted, researchers found that the electrical properties of the whole material differed markedly from typical graphite. And when they turned on a magnetic field, electrons deep in the graphite crystal adopted unusual properties similar to those of electrons at the twisted interface. Essentially, the single twisted graphene-graphite interface became inextricably mixed with the rest of the bulk graphite.

“Though we were generating the moiré pattern only at the surface of the graphite, the resulting properties were bleeding across the whole crystal,” said co-lead author , a UW postdoctoral researcher in physics.

For 2D sheets, moiré patterns generate properties that could be useful for quantum computing and other applications. Inducing similar phenomena in 3D materials unlocks new approaches for studying unusual and exotic states of matter and how to bring them out of the laboratory and into our everyday lives.

“The entire crystal takes on this 2D state,” said co-lead author Ellis Thompson, a UW doctoral student in physics. “This is a fundamentally new way to affect electron behavior in a bulk material.”

Yankowitz and his team believe their approach of generating a twist angle between graphene and a bulk graphite crystal could be used to create 2D-3D hybrids of its sister materials, including tungsten ditelluride and zirconium pentatelluride. This could unlock a new approach to re-engineering the properties of conventional bulk materials using a single 2D interface.

“This method could become a really rich playground for studying exciting new physical phenomena in materials with mixed 2D and 3D properties,” said Yankowitz.

Quantum computing could revolutionize our world. For specific and crucial tasks, it promises to be exponentially faster than the zero-or-one binary technology that underlies today’s machines, from supercomputers in laboratories to smartphones in our pockets. But developing quantum computers hinges on building a stable network of qubits — or quantum bits — to store information, access it and perform computations.

Yet the qubit platforms unveiled to date have a common problem: They tend to be delicate and vulnerable to outside disturbances. Even a stray photon can cause trouble. Developing fault-tolerant qubits — which would be immune to external perturbations — could be the ultimate solution to this challenge.

A team led by scientists and engineers at the ������˾�� has announced a significant advancement in this quest. In a pair of papers published and , they report that, in experiments with flakes of semiconductor materials — each only a single layer of atoms thick — they detected signatures of “fractional quantum anomalous Hall” (FQAH) states. The team’s discoveries mark a first and promising step in constructing a type of fault-tolerant qubit because FQAH states can host anyons — strange “quasiparticles” that have only a fraction of an electron’s charge. Some types of anyons can be used to make what are called “topologically protected” qubits, which are stable against any small, local disturbances.

“This really establishes a new paradigm for studying quantum physics with fractional excitations in the future,” said , the lead researcher behind these discoveries, who is also the Boeing Distinguished Professor of Physics and a professor of materials science and engineering at the UW.

FQAH states are related to the , an exotic phase of matter that exists in two-dimensional systems. In these states, electrical conductivity is constrained to precise fractions of a constant known as the conductance quantum. But fractional quantum Hall systems typically require massive magnetic fields to keep them stable, making them impractical for applications in quantum computing. The FQAH state has no such requirement — it is stable even “at zero magnetic field,” according to the team.

Hosting such an exotic phase of matter required the researchers to build an artificial lattice with exotic properties. They stacked two atomically thin flakes of the semiconductor material molybdenum ditelluride (MoTe₂) at small, mutual “twist” angles relative to one another. This configuration formed a synthetic “honeycomb lattice” for electrons. When researchers cooled the stacked slices to a few degrees above absolute zero, an intrinsic magnetism arose in the system. The intrinsic magnetism takes the place of the strong magnetic field typically required for the fractional quantum Hall state. Using lasers as probes, the researchers detected signatures of the FQAH effect, a major step forward in unlocking the power of anyons for quantum computing.

The team — which also includes scientists at the University of Hong Kong, the National Institute for Materials Science in Japan, Boston College and the Massachusetts Institute of Technology — envisions their system as a powerful platform to develop a deeper understanding of anyons, which have very different properties from everyday particles like electrons. Anyons are quasiparticles — or particle-like “excitations” — that can act as fractions of an electron. In future work with their experimental system, the researchers hope to discover an even more exotic version of this type of quasiparticle: “non-Abelian” anyons, which could be used as topological qubits. Wrapping — or “braiding” — the non-Abelian anyons around each other In this quantum state, information is essentially “spread out” over the entire system and resistant to local disturbances — forming the basis of topological qubits and a major advancement over the capabilities of current quantum computers.

“This type of topological qubit would be fundamentally different from those that can be created now,” said UW physics doctoral student Eric Anderson, who is lead author of the Science paper and co-lead author of the Nature paper. “The strange behavior of non-Abelian anyons would make them much more robust as a quantum computing platform.”

Three key properties, all of which existed simultaneously in the researchers’ experimental setup, allowed FQAH states to emerge:

• Magnetism: Though MoTe₂ is not a magnetic material, when they loaded the system with positive charges, a “spontaneous spin order” — a form of magnetism called ferromagnetism — emerged.
• Topology: Electrical charges within their system have “twisted bands,” similar to a Möbius strip, which helps make the system topological.
• Interactions: The charges within their experimental system interact strongly enough to stabilize the FQAH state.

The team hopes that, using their approach, non-Abelian anyons await for discovery.

“The observed signatures of the fractional quantum anomalous Hall effect are inspiring,” said UW physics doctoral student , co-lead author on the Nature paper and co-author of the Science paper. “The fruitful quantum states in the system can be a laboratory-on-a-chip for discovering new physics in two dimensions, and also new devices for quantum applications.”

“Our work provides clear evidence of the long-sought FQAH states,” said Xu, who is also a member of the Molecular Engineering and Sciences Institute, the Institute for Nano-Engineered Systems and the Clean Energy Institute, all at UW. “We are currently working on electrical transport measurements, which could provide direct and unambiguous evidence of fractional excitations at zero magnetic field.”

The team believes that, with their approach, investigating and manipulating these unusual FQAH states can become commonplace — accelerating the quantum computing journey.
