Wetting of an Ising system with perfect and corrugated surfaces in a transverse field

Using the mean field theory, a comparative study of the wetting and layering transitions of a spin-1/2 Ising model with perfect and corrugated surfaces, is established. The phase diagrams are investigated and compared in the presence of both a longitudinal and surface fields. The effect of increasing the temperature and the transverse field on the wetting and layering transitions is outlined.

Layering transitions of the spin-1/2 Ising model in a transverse magnetic field

Using mean field theory, the effect of the transverse magnetic field on the layering and wetting transitions of the spin-1/2 Ising model with longitudinal magnetic field is studied. At a fixed value of the temperature smaller than the wetting temperature, such system exibits a sequence of layering transitions above a critical value of the transverse magnetic field, wich depends on the temperature and surface magnetic field.
