Title: Metastability for the Disordered Curie Weiss Potts model
Abstract:
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 q-spin Potts model (CWP), where the interaction coefficients between spins are general independent random variables. This model comprises also, e.g., the CWP model on inhomogeneous dense random graphs.
We give a general overview of metastability phenomenons, we provide quantitative and cualitative description, in addition to provide mathematically rigorous definition.
We are interested in a comparison of the metastable behavior of the CWP and the DCWP models, for fixed temperature and the infinite volume limit. We prove the CWP model is metastable and through this prove metastability for the DCWP model.
