Critical Wetting in Three Dimensions

A critical wetting (or interface delocalization) transition occurs when the interface between two fluid phases becomes infinitesimally bound to an attracting wall. It is shown that the critical exponents at this transition depend continuously on the parameter ω≡k_BT_w(4πξ_b²σ), where σ is the surface tension of the free interface, ξ_b is the bulk correlation length in the attracted fluid phase, and T_w is the transition temperature.
