SUMMARY:BCS-BEC Crossover in Ultracold Atoms: Quantum Fluctuations and
  Vortices\, R. G. Herb Condensed Matter Seminar\, Mohit Randeria\, Ohi
 o State University
DESCRIPTION:I will first introduce the problem of the BCS-BEC crossove
 r in a Fermi gas with arbitrary interactions and describe the progress
  in realizing these ideas in experiments with ultracold atomic gases. 
 I will then discuss three questions: (1) How quantum fluctuations abou
 t the mean field state impact observable properties in the crossover\;
  (2) How the vortex and core states evolve from the BCS to the BEC lim
 its\; (3) Why the most strongly interacting regime at unitarity leads 
 to the most robust superfluid in the entire crossover.
