Effects due to finite values of the temperature and the chemical potential in some two-dimensional field models
Description
A study is made in the mean field approximation of the ground-state structure of the Gross-Neveu model as N → ∞ and the two-dimensional (1 + 1) /var phi/4 model with fermions at finite values of the temperature T and chemical potential α of the fermions. The critical values T/sub c/ and α/sub c/ at which the symmetry of the system, which is spontaneously broken at T = α = 0, is restored are obtained. The possibility of using the obtained results to describe the physical property is of quasione-dimensional systems in the theory of condensed media is discussed
