Phase Transition of Laminated Models at Any Temperature

Mathematical Physics 2010-02-19 v1 math.MP

Abstract

The standard Pirogov -- Sinai theory is generalized to the class of models with two modes of interaction: longitudinal and transversal. Under rather general assumptions about the longitudinal interaction and for one specific form of the transversal interaction it is proved that such system has a variety of phase transitions at any temperature: the parameter which plays the role of inverse temperature is the strength of the transversal interaction. The concrete examples of such systems are (1+1)(1+1)-dimensional models.
