DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Kadanoff/8/"
 >Fermi seas from Bose condensates and a bosonic exclusion principle in mat
 ter Chern Simons theories</a>\nby Shiraz Minwalla (TIFR Mumbai) as part of
  Kadanoff seminars\n\n\nAbstract\nI will study Chern Simons gauge theories
  in three dimensions coupled to (bosonic or fermionic) matter in the funda
 mental representation in the large N limit. I will first explain how previ
 ously obtained results for the thermal free energy in these theories can b
 e generalized to values of the chemical potential that are larger than qua
 si particle mases. I will then use these results to find a  simple explici
 t formula for the occupation number for a bosonic quasiparticle state of a
 ny given energy and charge as a function of the temperature and chemical p
 otential. This formula is a generalization to finite 't Hooft coupling of 
 the famous result of Bose-Einstein statistics. It implies the following  e
 xclusion principle for large N  Chern Simons coupled bosons: the total num
 ber of bosons occupying any single state cannot exceed the Chern Simons le
 vel. Specializing to zero temperature I will also  construct the phase dia
 grams of these theories  as a function of chemical potential and the UV pa
 rameters. The phase diagram includes a Bose condensed phase\, dual to the 
 Fermionic Fermi sea. The runaway instability of free theories at large che
 mical potential is cured by the bosonic exclusion principle.\n
