The 2d Gross-Neveu Model at Finite Temperature and Density with Finite N Corrections
We use the linear d expansion, or optimized perturbation theory, to evaluate the effective potential for the twodimensional Gross-Neveu model at finite temperature and density obtaining analytical equations for the criticaltemperature, chemical potential and fermionic mass which include finite N cor...
