Finite Temperature Effective Potential in the Hartree-Fock Approximation

Abstract

In order to investigate the nature of the phase transition, we study the finite temperature effective potential for the $\lambda {\Phi }^4$ theory in the Hartree-Fock approximation, which sums up all the daisy and superdaisy diagrams.
