Modulated structures in a Lebwohl-Lasher model with chiral interactions
E. S. Nascimento, A. Petri, S. R. Salinas
We consider a Lebwohl-Lasher lattice model with nematic directors restricted to point along planar directions. This Lebwohl-Lasher system is the nematic analogue of the st…
Anomalous metastability in a temperature-driven transition
Miguel Ibáñez Berganza, Pietro Coletti, Alberto Petri
Langer theory of metastability provides a description of the lifetime and properties of the metastable phase of the Ising model field-driven transition, describing the magnetic fie…
Non-equilibrium fluctuations in frictional granular motor: experiments and kinetic theory
Andrea Gnoli, Alessandro Sarracino, Alberto Petri +1
We report the study of a new experimental granular Brownian motor, inspired to the one published in [Phys. Rev. Lett. 104, 248001 (2010)], but different in some ingredients. As in…
Stochastic dynamics of a sheared granular medium
Alberto Petri, Andrea Baldassarri, Fergal Dalton +3
We experimentally investigate the response of a sheared granular medium in a Couette geometry. The apparatus exhibits the expected stick-slip motion and we probe it in the very int…
Ordering dynamics in the presence of multiple phases
Alberto Petri, Miguel Ibanez de Berganza, Vittorio Loreto
The dynamics of the 2D Potts ferromagnet when quenched below the transition temperature is investigated in the case of discontinuous phase transition, which is interesting for unde…
Dynamic metastability in the two-dimensional Potts ferromagnet
Miguel Ibáñez Berganza, Alberto Petri, Pietro Coletti
We investigate the non-equilibrium dynamics of the 2D Potts model on the square lattice after a quench below the discontinuous transition point. By means of numerical simulations o…
