Inverse symmetry breaking phenomena for thermal phase transition in binary - mixture boson systems

Abstract

    Thermal phase transition in binary - mixture boson systems is studied by means of the Cornwall Jackiw - Tomboulis effective potential approach in the improved double - bubble approximation which preserves the Goldstone theorem. Its main feature is that the transition is second order occurring when the temperature is reduced to critical value associating with two types including inverse symmetry breaking transition and symmetry restoration transition.
