Reservoirs, Fick law and the Darken effect
Anna De Masi, Immacolata Merola, Errico Presutti
We study the stationary measures of Ginzburg-Landau (GL) stochastic processes which describe the magnetization flux induced by the interaction with reservoirs. To privilege simplic…
Renewal properties of the Ising model
Marzio Cassandro, Immacolata Merola, Errico Presutti
We consider the Ising model with Kac potentials at inverse temperature where mean field predicts a phase transition with two possible equilibrium magnetization $\pm m_β…
Phase separation for the long range one--dimensional ising model
Marzio Cassandro, Immacolata Merola, Pierre Picco
We consider the phase separation problem for the one--dimensional ferromagnetic Ising model with long--range two--body interaction, $J(n)=n^{-2+\a}$ where denotes the dis…
Study of a long range perturbation of a one-dimensional Kac model
Marzio Cassandro, Immacolata Merola, Maria Eulalia Vares
We consider a one dimensional ferromagnetic Ising spin system with interactions that correspond to a long range perturbation of the usual Kac model. We apply a coarse grain…
Coexistence of ordered and disordered phases in Potts models in the continuum
Anna De Masi, Immacolata Merola, Errico Presutti +1
This is the second of two papers on a continuum version of the Potts model, where particles are points in , , with a spin which may take possible valu…
First-Order Phase Transition in Potts Models with finite-range interactions
Thierry Gobron, Immacolata Merola
We consider the -state Potts model on , , , with Kac ferromagnetic interactions and scaling parameter $\ga$. We prove the existence of a first order…
