The Ising Model on a Two-Community Stochastic Block Model
Alessandra Bianchi, Vanessa Jacquier, Matteo Sfragara
We study the Ising model on a two-community stochastic block model, where spins are split into two equal groups with inter-community interaction parameter . We pro…

Particle transport based study of nucleation in a ferromagnetic three-state spin system with conservative dynamics
Vanessa Jacquier, Emilio Nicola Maria Cirillo, Cristian Spitoni
We pose the problem of metastability for a three--state spin system with conservative dynamics. We consider the Blume--Capel model with the Kawasaki dynamics, we prove that, in a p…
