Abstract

Description

We consider a zero-field Ising model defined on a quasiperiodic graph, the so-called Labyrinth tiling. Exact information about the critical behaviour is obtained from duality arguments and the subclass of models which yield commuting transfer matrices. For the latter, the magnetization is independent of the position and the phase transition between ordered and disordered phase belongs to the Onsager universality class. In order to obtain information about the generic case, we calculate the magnetization for a series of couplings by standard Monte-Carlo methods.
