Geometrical properties of Potts model during the coarsening regime
Marcos P. O. Loureiro, Jeferson J. Arenzon, Leticia F. Cugliandolo
We study the dynamic evolution of geometric structures in a poly-degenerate system represented by a -state Potts model with non-conserved order parameter that is quenched from i…
Critical Langevin dynamics of the O(N)-Ginzburg-Landau model with correlated noise
Julius Bonart, Leticia F. Cugliandolo, Andrea Gambassi
We use the perturbative renormalization group to study classical stochastic processes with memory. We focus on the generalized Langevin dynamics of the ϕ^4 Ginzburg-Landau model wi…
Fluctuation-dissipation relations and critical quenches in the transverse field Ising chain
Laura Foini, Leticia F. Cugliandolo, Andrea Gambassi
Dynamic correlation and response functions of classical and quantum systems in thermal equilibrium are connected by fluctuation-dissipation theorems, which allow an alternative def…
Out of equilibrium dynamics in the bidimensional spin-ice model
Demian Levis, Leticia F. Cugliandolo
We study the dynamics of 2d spin-ice following a quench from a fully disordered initial condition (equilibrium at infinite temperature) into its disordered, ferromagnetic and antif…
Fluctuations of two-time quantities and time-reparametrization invariance in spin-glasses
Claudio Chamon, Federico Corberi, Leticia F. Cugliandolo
This article is a contribution to the understanding of fluctuations in the out of equilibrium dynamics of glassy systems. By extending theoretical ideas based on the assumption tha…
Non-conservative forces and effective temperatures in active polymers
Davide Loi, Stefano Mossa, Leticia F. Cugliandolo
We follow the dynamics of an ensemble of interacting self-propelled semi-flexible polymers in contact with a thermal bath. We characterize structure and dynamics of the passive sys…
