Query: The Polyakov loop models in the large N limit: Phase diagram at finite
  density   The 't Hooft-Veneziano limit of various U(N) and SU(N) Polyakov loop models
is constructed at finite temperature and non-zero baryon chemical potential. In
this paper we calculate the free energy, its derivatives, the Polyakov loop
expectation values and the baryon density. The phase diagram is described in
details.
