Surface Phase Transitions

A Brief Description

Using a three-state Potts model, we have shown that surface melting can be observed close to the triple point. We have calculated the density profile of a slab of finite layers in the mean-field approximation. We find that a liquid film is developed in the density profile at temperatures close to the triple point. It is shown that the thickening of this quasi-liquid film grows logarithmically as one approaches the triple point which is similar to what one observes for systems governed by short-range forces.
