How many phases nucleate in the bidimensional Potts model?

Autor: Federico Corberi, Leticia F Cugliandolo, Marco Esposito, Onofrio Mazzarisi, Marco Picco

We study the kinetics of the two-dimensional q > 4-state Potts model after a shallow quench slightly below the critical temperature and above the pseudo spinodal. We use numerical methods and we focus on intermediate values of q, 4 < q < 100. We show

Maximal Diversity and Zipf’s Law

Autor: Jeferson J. Arenzon, Onofrio Mazzarisi, Federico Corberi, Amanda de Azevedo-Lopes

Publikováno v: Physical Review Letters. 127

Zipf's law describes the empirical size distribution of the components of many systems in natural and social sciences and humanities. We show, by solving a statistical model, that Zipf's law co-occurs with the maximization of the diversity of the com

Metastability in the Potts model: exact results in the large q limit

Autor: Onofrio Mazzarisi, Marco Picco, Leticia F. Cugliandolo, Federico Corberi

Journal of Statistical Mechanics: Theory and Experiment, IOP Publishing, 2020, 2020 (6), pp.063214. ⟨10.1088/1742-5468/ab8556⟩

We study the metastable equilibrium properties of the Potts model with heat-bath transition rates using a novel expansion. The method is especially powerful for large number of state spin variables and it is notably accurate in a rather wide range of

Dynamics of fluctuations in the Gaussian model with conserved dynamics

Autor: Andrea Gambassi, Federico Corberi, Onofrio Mazzarisi

We study the fluctuations of the Gaussian model, with conservation of the order parameter, evolving in contact with a thermal bath quenched from inverse temperature $\beta _i$ to a final one $\beta _f$. At every time there exists a critical value $s_

Dynamics of fluctuations in the Gaussian model with dissipative Langevin Dynamics

Autor: Onofrio Mazzarisi, Federico Corberi, Andrea Gambassi

We study the dynamics of the fluctuations of the variance $s$ of the order parameter of the Gaussian model, following a temperature quench of the thermal bath. At each time $t$, there is a critical value $s_c(t)$ of $s$ such that fluctuations with $s
