People Profiles

Efim Rozenbaum

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.
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.
Aftaab Dewan

Aftaab Dewan, a graduate fellow at JQI, received undergraduate degrees in physics and mathematics at Amherst College. There, he was a recipient of the Bassett Prize and the Stifler Prize, and conducted research on studying dynamics of Bose-Einstein Condensates. His senior thesis examined how neutrinos scatter off of materials such as lead or glass. He now works with Steve Rolston to understand the transport, coherence, and delocalization properties of BECs. Analyzing the interactions within and between regions of a BEC adds to the ultimate goal of building a quantum simulator.
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.
Michael Foss-Feig

Michael Foss-Feig is a JQI postdoctoral scientist. As an undergraduate at Amherst College, Michael performed some experimental work in solid-state physics with professor Jonathan Friedman. He, then, went to University of Colorado where he received a physics PhD in October 2012. His thesis, prepared under the supervision of Ana Maria Rey, was entitled “Quantum simulation of many-body physics with neutral atoms, molecules and ions.” This work earned him the DAMOP Thesis Prize in June 2013. Now a NRC postdoctoral fellow at NIST working under Charles Clark, Michael’s interests are centered around many-body physics with ultracold atomic, molecular, and optical systems. He also studies long-range interacting systems, such as trapped ions, ultracold dipolar molecules, and Rydberg atoms.
Mary Lyon

Mary Lyon is originally from Princeton, New Jersey. She attended Bryn Mawr College, where she earned both her undergraduate degree in physics and a high school teaching certificate. Lyon originally planned to be a high school physics teacher, but discovered a love for research during a summer program at MIT the summer after her junior year. She briefly taught high school in Columbus, GA before going to graduate school at Brigham Young University, where she worked with Scott Bergeson on strongly coupled ultracold neutral plasmas. She is currently a JQI postdoctoral researcher in the group of Trey Porto and Steve Rolston where she is building a new quantum information experiment that will use an ensemble of cold Rydberg atoms.
