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

TL;DR

This paper investigates how a transverse magnetic field influences layering and wetting transitions in a spin-1/2 Ising model using mean field theory, revealing a sequence of transitions dependent on temperature and surface field.

Contribution

It introduces a mean field theoretical analysis of the impact of transverse magnetic fields on layering transitions in the Ising model, highlighting critical field dependencies.

Findings

Layering transitions occur above a critical transverse magnetic field.

The critical field depends on temperature and surface magnetic field.

Sequence of layering transitions is observed below the wetting temperature.

Abstract

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.
