Using optimized perturbation theory, we evaluate the effective potential for the massless two dimensional Gross-Neveu model at finite temperature and density containing corrections beyond the leading large-N contribution. For large-N , our results exactly reproduce the well known 1/N leading order results for the critical temperature, chemical potential and… CONTINUE READING
