Monte Carlo Test of Theories for the Planar Model, theFModel, and Related Systems

Abstract
We have performed Monte Carlo simulations for correlation functions in various solid-on-solid models, some of which are equivalent to the F model, the two-dimensional Coulomb gas, and the planar model. Our results for the F model can be quantitatively represented using the theory of Kosterlitz and Thouless. We use this theory to help determine the transition temperatures in other systems.
