Critical coupling thresholds for tilted Kuramoto-Vicsek models with a confining potential
Benedetta Bertoli, Benjamin D. Goddard, Grigorios A. Pavliotis
We study a Kuramoto-Vicsek model of self-propelled particles with periodic boundary conditions subject to a constant angular tilt and a confining potential, and its mean-field (Fok…

Phase transitions for interacting particle systems on random graphs
Benedetta Bertoli, Grigorios A. Pavliotis, Niccolò Zagli
In this paper, we study weakly interacting diffusion processes on random graphs. Our main focus is on the properties of the mean-field limit and, in particular, on the nonuniquenes…

Stability of stationary states for mean field models with multichromatic interaction potentials
Benedetta Bertoli, Benjamin D. Goddard, Grigorios A. Pavliotis
We consider weakly interacting diffusions on the torus, for multichromatic interaction potentials. We consider interaction potentials that are not H-stable, leading to phase transi…
