概要

We have applied the recently proposed renormalization group improvement procedure of the finite temperature effective potential, and have investigated extensively the phase structure of the massive scalar φ^4 model, showing that the φ^4 model has a rich 3-phase structure at T ≠ 0, two of them are not seen in the ordinary perturbative analysis. Temperature dependent phase transition in this model is shown to be strongly the first order.
