Researchers have found that a small stretch is enough to unleash the exotic electrical properties of a recently discovered topological insulator, unshackling a behavior previously locked away at cryogenic temperatures.The compound, called samarium hexaboride, has been studied for decades. But recently it has enjoyed a surge of renewed interest as scientists ... Continue Reading
Lauren Aycock, a recent JQI graduate researcher, has been awarded a Congressional Science Fellowship from the American Physical Society.The fellowship, which lasts for one year, aims to provide members of Congress with the scientific and technical expertise of trained scientists. In turn, fellows like Aycock get to learn first-hand about public policy and communicate with Congress on behalf of... Continue Reading
Trapped ions and superconductors face off in quantum benchmark
The race to build larger and larger quantum computers is heating up, with several technologies competing for a role in future devices. Each potential platform has strengths and weaknesses, but little has been done to directly compare the performance of early prototypes. Now, researchers at the JQI have performed a first-of-its-kind benchmark test of two small quantum computers built from... Continue Reading

Physics professor and JQI Fellow Fred Wellstood has been appointed the newest UMD Co-Director of JQI. He assumed the role on March 1."Fred has played a major role in the JQI since its founding," says Gretchen Campbell, the current NIST Co-Director of JQI. "Most recently, his tireless efforts helped to design and ultimately build the new Physical Sciences Center at Maryland that many JQI labs... Continue Reading
Efim Rozenbaum is a graduate fellow at JQI who studied physics as an undergraduate and graduate student at St. Petersburg State University. His undergraduate thesis focused on new numerical methods for solving the equations that govern quantum systems with axial symmetry, and his Master’s thesis continued this work for highly charged heavy ions. Now, he works with JQI and the Condensed Matter Theory Center to study the effect of interactions on dynamical localization, the signatures of chaotic transitions in quantum dynamics and non-Markovian soliton dynamics with non-Ohmic friction.
Elizabeth Goldschmidt recently joined the quantum information science group at the Army Research Laboratory. She earned an undergraduate degree in physics at Harvard University. After, she went on to earn a PhD at JQI, where as part of Alan Migdall's research group, she worked on quantum memory and single photon technologies. She then received a National Research Council postdoctoral fellowship at NIST to work with Trey Porto on simulating condensed matter systems with ultracold atoms trapped in optical lattices. In her position at the Army Research Lab, she is starting a new experimental research program focused on quantum memory and quantum information in solid-state materials.
Former NRC postdoctoral fellow Steven Olmschenk is currently faculty at Denison University located in Granville, Ohio. Steve was a graduate student in Chris Monroe’s Trapped Ion Quantum Information group and then a postdoc in the NIST Laser Cooling and Trapping Group. While at NIST he worked on Trey Porto’s double-well optical lattice experiment. At Dension he has a group researching physics at the interface of quantum optics and trapped atomic ions http://personal.denison.edu/~olmschenks/.
Xiapeng Li is a JQI Postdoctoral Fellow working in CMTC. His research interest is primarily in quantum condensed matter. His work covers novel states of matter in both well-controlled ultracold atomic systems and in complex electronic materials. He has been have been studying a broad range of systems, such as atomic p-orbital systems in optical lattices, dipolar quantum gases, and complex oxides. Some of his current efforts focus on (1) emergent spin orbital couplings and gauge fields in spinor Bose gases and Bose-Fermi mixtures as well as (2) band crossing and multi-orbital superconductivity, spin spirals and skyrmions in oxides and heterostructures. Li received his Ph.D. from the University of Pittsburgh and was an undergraduate at the University of Science and Technology of China, Hefei, Anhui, China.
Ryan Barnett, a former JQI postdoctoral fellow at the Condensed Matter Theory Center (CMTC), is now a ‘Lecturer in Condensed Matter Theory’ (UK equivalent of assistant professor) at Imperial College in London. Ryan is a theoretical physicist interested in collective effects in ultracold atomic gases. While at the JQI his research focused on spinor condensates, non-equilibrium dynamics, and synthetic gauge fields. Much of his recent work at CMTC was motivated by ongoing experimental activities at the JQI.
James R. Williams
James R. Williams is a JQI Fellow and assistant professor of physics, and his chief area of research is experimental condensed matter physics. Specifically, he specializes in understanding why certain one and two-dimensional materials (e.g. topological insulators, graphene) depart from normal conductivity provided by free electrons. Dr. Williams received his bachelors in engineering physics at Santa Clara University. He then went on to get his MS and PhD from Harvard University in 2009 on the subject of grapheme, while studying under Charles M. Marcus. He was then a postdoctoral fellow at Stanford before coming to Maryland.
