Metastability for the Curie-Weiss-Potts model with unbounded random interactions
Johan L. A. Dubbeldam, Vicente Lenz Burnier, Elena Pulvirenti +1
We analyse the metastable behaviour of the disordered Curie--Weiss--Potts (DCWP) model subject to a Glauber dynamics. The model is a randomly disordered version of the mean-field $…
The Widom-Rowlinson model: Mesoscopic fluctuations for the critical droplet
Frank den Hollander, Sabine Jansen, Roman Kotecký +1
We study the critical droplet for a close-to-equilibrium Widom-Rowlinson model of interacting particles, represented by disks of radius , in the two-dimensional plane at low tem…
Hydrodynamic limit and large deviations for run-and-tumble particles with mean-field switching rates
Elena Pulvirenti, Frank Redig, Hidde van Wiechen
In this paper, we study run-and-tumble particles moving on two copies of the discrete torus (referred to as layers), where the switching rate between layers depends on a mean-field…
Metastability of Glauber dynamics with inhomogeneous coupling disorder
Anton Bovier, Frank den Hollander, Saeda Marello +2
We introduce a general class of mean-field-like spin systems with random couplings that comprises both the Ising model on inhomogeneous dense random graphs and the randomly diluted…
