People Profiles

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.
Dong-Ling Deng

Dong-Ling Deng is a JQI Postdoctoral Fellow working in the Condensed Matter Theory Center at UMD. He received his PhD in physics from the University of Michigan, and his research interests include quantum information theory and topological phases of matter. He has proposed a new kind of random number generator based on Majorana fermions, which would be able to generate random numbers with unconditional security. Outside of working hours Deng loves to read classic Chinese novels and play badminton.
Gretchen Campbell

Campbell is a NIST JQI fellow and works in the Laser Cooling and Trapping group. In her atom circuits lab, reserachers probe Na BECs in toroidal traps. The goals of these experiments include studying superfluidity, as well as superfluid analogs to superconducting circuits. A second experiment with ultracold strontium is being built. She received a Ph.D from MIT in 2006, where she worked with Wolfgang Ketterle and Dave Pritchard. There, she used Rb BECs in optical lattices to study atom interferometry, nonlinear atom optics and the superfluid – Mott insulator phase transition. These experiments included the first direct observation of the atomic recoil momentum in dispersive media. More recently, she worked with Jun Ye on precision measurements and frequency metrology with an ⁸⁷Sr optical lattice clock.
Xiaopeng Li

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.
Aaron Lee

Aaron Lee, a JQI graduate student, received his undergraduate degree in physics at UMD. He worked with Chris Monroe’s trapped ion group, using ytterbium ions to simulate other quantum systems. As a graduate student, he has continued to study quantum information with the Monroe group and hopes his work can contribute to eventually building a quantum computer.
Mohammad Hafezi

Hafezi is JQI fellow and works at the interface of condensed matter theory and quantum optics. The focus of his research is on theoretical and experimental investigations of artificial gauge fields and topological order in photonics systems. Such systems can be exploited as robust optical devices insensitive to disorder, which is the subject of his NSF Physics Frontier Center’s seed funding program. Moreover, in the presence of strong optical nonlinearity, such systems are expected to exhibit fractional quantum Hall physics, providing a platform for potentially observing anoynic statistics. He received his Ph.D. from Harvard in 2009 where he worked with Mikhail Lukin and Eugene Demler. There, he studied strongly correlated physics in AMO systems. In particular, he worked on the topological characterization of ultracold atoms in 2D and also non-equilibrium dynamics of strongly interacting photons in 1D.
