First-order transitions for very nonlinear sigma models
arXiv:cond-mat/0506730
Abstract
In this contribution we discuss the occurrence of first-order transitions in temperature in various short-range lattice models with a rotation symmetry. Such transitions turn out to be widespread under the condition that the interaction potentials are sufficiently nonlinear.
