Nonequilibrium Critical Dynamics of the 2D XY model
Ludovic Berthier, Peter C. W. Holdsworth, Mauro Sellitto
The nonequilibrium critical dynamics of the 2D XY model is investigated numerically through Monte Carlo simulations and analytically in the spin-wave approximation. We focus in par…
Phase separation in an homogeneous shear flow: Morphology, growth laws and dynamic scaling
Ludovic Berthier
We investigate numerically the influence of an homogeneous shear flow on the spinodal decomposition of a binary mixture by solving the Cahn-Hilliard equation in a two-dimensional g…
Glassy systems under time-dependent driving forces: application to slow granular rheology
Ludovic Berthier, Leticia F. Cugliandolo, Jose Luis Iguain
We study the dynamics of a glassy model with infinite range interactions externally driven by an oscillatory force. We find a well-defined transition in the (Temperature-Amplitude-…
Sub-aging in a Domain Growth Model
Ludovic Berthier
We study analytically the aging dynamics of the O(n) model in the large-n limit, with conserved and with non-conserved order parameter. While in the non-conserved dynamics, the aut…
