Tricritical Behavior of Two-Dimensional Scalar Field Theories

Abstract

We compute by Monte Carlo numerical simulations the critical exponents of two-dimensional scalar field theories at the $\lambda {\varphi }^6$ tricritical point. The results are in agreement with the Zamolodchikov conjecture based on conformal invariance.
