Please join us for an informal seminar sponsored by the Atomic and Molecular Physics Division, Harvard-Smithsonian Center for Astrophysics. (Complete schedule at http://www.cfa.harvard.edu/amp/events.html) 2:00 PM Monday April 4, 2011 PRATT Conference Room 60 Garden St., Cambridge, MA 02138 Highly polarized Fermi gases in different dimensions Dr. Meera Parish Princeton Center for Theoretical Science, Princeton University In this talk, I will consider an atomic Fermi gas in the limit of extreme spin imbalance, where one has a single spin-down impurity atom interacting attractively with a spin-up atomic Fermi gas. Such a scenario is an example of the canonical "polaron" problem, the solution of which is used to construct the low-energy behavior of many-body systems. For sufficiently strong attraction, the impurity atom has the possibility of binding one or more spin-up fermions and thus changing its statistics. I will explore the nature of these binding transitions and how they are affected by the system dimensionality. _______________________________________________ Aspuru-meetings-list mailing list Aspuru-meetings-list(a)lists.fas.harvard.edu http://lists.fas.harvard.edu/mailman/listinfo/aspuru-meetings-list
