Low-temperature interfaces: prewetting, layering, faceting and Ferrari-Spohn diffusions. (English) Zbl 1414.60079
Summary: n this paper, we survey and discuss various surface phenomena such as prewetting, layering and faceting for a family of two- and three-dimensional low-temperature models of statistical mechanics, notably Ising models and $$2+1$$-dimensional solid-on-solid (SOS) models, with a particular accent on scaling regimes which lead or, in most cases, are conjectured to lead to Ferrari-Spohn type diffusions.
