People Profiles

Gretchen Campbell, Fellow

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.
Steven Olmshenck

NRC postdoctoral fellow Steven Olmschenk will be joining the faculty at Denison University located in Granville, Ohio. Steve was a graduate student in Chris Monroe’s Trapped Ion Quantum Information group. For the last few years he has been a postdoc in the NIST Laser Cooling and Trapping Group. While at NIST he has worked on Trey Porto’s double-well optical lattice experiment. Upon moving to Dension he plans to build an ion trapping experiment.
Wes Campbell

Wes Campbell will join the faculty at UCLA in the fall, where he plans to build up a lab to study cold molecules and trapped ions. His cold molecule research is an outgrowth of the NSF Physics Frontier Center’s seed funding program, here at JQI. The seed funding program is a competitive opportunity for postdocs to apply for PFC funding to support an independent project. Since 2008, Wes has been doing research in Chris Monroe’s trapped ion quantum information group. Wes was instrumental in constructing an experiment that focuses on ultrafast gates with ions. During the last year he has also worked on quantum simulations of magnetism with ion chains.
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. He will help organize the Nordita program “Pushing the boundaries with cold atoms,” to be held in early 2013. 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.”
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 was motivated by ongoing experimental activities at the JQI. In addition to continuing this line of research, he will teach Mathematical Physics during the 2012-2013 academic year.
Mohammad Hafezi

Hafezi is a senior research associate 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.
