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, 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.”
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.
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.
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.
David Hucul is a graduate student in Professor Chris Monroe's trapped ion quantum information lab at the Joint Quantum Institute. He earned undergraduate degrees in physics and chemistry in 2006 from the University of Michigan and a master's degree at MIT in 2009 under Wolfgang Ketterle. David started his PhD work with Chris Monroe in 2009 working on using frequency combs to entangle trapped ions. He now works on entangling trapped atoms within and between ion traps using both phonons and photons to create quantum networks.
David became interested in atomic physics by accident, when he enjoyed an advanced chemistry course about spectroscopy and realized it was really physics. His first physics seminar was given by Chris Monroe, who was then a professor at Michigan. This made him a physicist.
He expects to finish his graduate studies sometime in 2015 and hopes to find a postdoctoral position after that.
