Fluid-fluid demixing curves for colloid-polymer mixtures in a random colloidal matrix
Mario Alberto Annunziata, Andrea Pelissetto
We study fluid-fluid phase separation in a colloid-polymer mixture adsorbed in a colloidal porous matrix close to the θ-point. For this purpose we consider the Asakura-Oosawa model…
Ferromagnetic-glassy transitions in three-dimensional Ising spin glasses
Giacomo Ceccarelli, Andrea Pelissetto, Ettore Vicari
We investigate the ferromagnetic-glassy transitions which separate the low-temperature ferromagnetic and spin-glass phases in the temperature-disorder phase diagram of three-dimens…
Finite-size scaling in two-dimensional Ising spin glass models
Francesco Parisen Toldin, Andrea Pelissetto, Ettore Vicari
We study the finite-size behavior of two-dimensional spin-glass models. We consider the +-J model for two different values of the probability of the antiferromagnetic bonds and the…
