Abstract

Finite-size-scaling analysis of a simulation of the critical behavior of a nonrandom three-dimensional frustrated system yields a tricritical-like behavior not predicted by a simple Landau-Ginzburg-Wilson theory. We argue that, because of the frustration, the free energy of many phases is close to that of the observed ordered phase and that a complete theory must take into account interactions between fluctuations of order parameters of all these phases. We suggest that these properties are generic to frustrated systems. Related transitions in the model are also discussed.
