Gentili colleghe e colleghi,

Vi segnalo con piacere il seguente seminario che si terrà Venerdì 22 Aprile dalle 9:30 alle 10:30 in modalità mista.

Location: Aula 215, Plesso Morgagni, Viale Giovan Battista Morgagni 40, 50134 Firenze Link alla videochiamata: https://meet.google.com/rps-uiyj-bhj https://meet.google.com/rps-uiyj-bhj

Speaker: Seonwoo Kim (Seoul National University) Title: Metastability of Ising/Potts models on lattices in the low-temperature regime Abstract: In this talk, I will discuss metastability of the Ising/Potts model with zero external field in two or three dimensions. Metastable transitions in the case of zero field occur along a large saddle plateau, which can be divided into bulk and edge parts. Transitions on the bulk part are one-dimensional and thus easy to analyze, whereas transitions on the edge part are much more complex. In two dimension, I will characterize them in a very precise manner. On the other hand in three dimension, it is impossible to find such a precise characterization and thus I present an alternative abstract method to analyze the metastable behavior. This talk is based on a joint work with Insuk Seo at Seoul National University.

Cordiali saluti, Gianmarco Bet
