Localization and delocalization of random interfaces

Yvan Velenik, CNRS and Université de Rouen


Abstract
The study of effective interface models has been quite active recently, with a particular emphasis on the effect of various external potentials (wall, pinning potential, ...) leading to localization/delocalization transitions. I review some of the results that have been obtained. In particular, I discuss pinning by a local potential, entropic repulsion and the (pre)wetting transition, both for models with continuous and discrete heights. This text is based on lecture notes for a mini-course given during the workshop "Topics in Random Interfaces and Directed Polymers" held in Leipzig, September 12-17 2005.

AMS 2000 subject classifications: Primary 60K35, 82B41; secondary 82B24, 82B27.

Keywords: random interfaces, random surfaces, roughening, entropic repulsion, pinning, wetting, prewetting.
