The relevance of the three dimensional Thirring coupling at finite temperature and density

Abstract

We studied the three dimensional Thirring model in the limit of infinite number of flavors at finite temperature and density. We calculated the number density as a function of temperature and the density at zero temperature serves as a relevant parameter. A three dimensional free fermion gas behavior as the density at zero temperature approaches zero smoothly crosses over to a two dimensional free fermion gas behavior as the density at zero temperature approaches infinity.
