People Profiles

Stephen Powell

Stephen Powell, a former JQI postdoctoral fellow at CMTC, now works at the Nordic Institute of Theoretical Physics or Nordita in Stockholm, Sweden. His research in the group of Sankar Das Sarma centered around strongly correlated systems with a specific focus on frustrated magnetism and ultracold gases. At Nordita, he will continue this line of research, which is at the meeting point of condensed matter and atomic physics. In talking of his postdoctoral experience he says, “Something I've particularly enjoyed about being at JQI is having close contact with various experimental groups here.”
Nicholas Grabon

Nicholas Grabon is a JQI graduate fellow who received an undergraduate degree in physics at the University of Wisconsin-Madison. There, he helped design silicon chips with embedded quantum logic. At JQI, he previously worked on the theory of topological states on a lattice containing individual sites. Now, he is working with Vladimir Manucharyan to build smaller resonators with higher quality, design (fluxonium) qubits with decreased noise and better understand many-body physics.
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.
Elizabeth Goldschmidt

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.
Ryan Barnett

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.
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.
