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…

On the Kertész line: Some rigorous bounds
Jean Ruiz, Marc Wouts
We study the Kertész line of the --state Potts model at (inverse) temperature , in presence of an external magnetic field . This line separates two regions of the phase di…

Lower Spectral Branches of a Spin-Boson Model
Nicolae Angelescu, Robert Minlos, Jean Ruiz +1
We study the structure of the spectrum of a two-level quantum system weakly coupled to a boson field (spin-boson model). Our analysis allows to avoid the cutoff in the number of bo…
