- Description
- We analyze the finite temperature chiral restoration transition of the (D=d+1) -dimensional Gross-Neveu model when the total fermion number is constrained to be fixed. This leads to the study of the model with a nonzero imaginary chemical potential. In this formulation of the theory, we have obtained that, in the transition region, the model is described by a chiral conformal field theory where the concepts of dimensional reduction and universality do apply and we have the realization of a "universal" scenario, in which the reduced theory belongs to the same universality class of the original one exhibiting the same symmetry breaking pattern.
