Query: High Temperature Phase Transition in Two-Scalar Theories   Two-scalar theories at high temperature exhibit a rich spectrum of possible
critical behaviour, with a second or first order phase transition. In the
vicinity of the critical temperature one can observe critical exponents,
tricritical points and crossover behaviour. None of these phenomena are visible
to high temperature perturbation theory.
