Description

The effects of nonperturbative configurations at finite temperature are investigated for a real scalar field theory that exhibits a spontaneous symmetry breaking at zero temperature. In 1+1 dimensions we find a zero-temperature phase transition due to kink-antikink pairs. In 3+1 dimensions we calculate the contribution of bubbles that have an interior region of different vacuum in the equi- librium finite-temperature theory. We find that the energy cost of bubble surfaces makes their effects negligible at temperature below the perturbatively calculated phase-transition temperature. We discuss the interpretation of these results
