Thermodynamic versus Topological Phase Transitions: Cusp in the Kertész Line
Philippe Blanchard, Daniel Gandolfo, Jean Ruiz +1
We present a study of phase transitions of the Curie--Weiss Potts model at (inverse) temperature , in presence of an external field . Both thermodynamic and topological aspec…

First-order transitions for very nonlinear sigma models
A. C. D. van Enter, S. B. Shlosman
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 t…
