Universal Critical Behavior of Noisy Coupled Oscillators
Thomas Risler, Jacques Prost, Frank Julicher
We study the universal thermodynamic properties of systems consisting of many coupled oscillators operating in the vicinity of a homogeneous oscillating instability. In the thermod…
Glassy properties of the Kawasaki dynamics of two-dimensional ferromagnets
Florent Krzakala
We study numerically the Kawasaki dynamics of the 2d Ising model. At large time we recover the coarsening growth as l(t) ~ t^(1/3). At shorter time however, the system enters a met…
Elastic wave propagation in confined granular systems
Ellak Somfai, Jean-Noel Roux, Jacco H. Snoeijer +2
We present numerical simulations of acoustic wave propagation in confined granular systems consisting of particles interacting with the three-dimensional Hertz-Mindlin force law. T…
Dynamics of granular avalanches caused by local perturbations
Thorsten Emig, Philippe Claudin, Jean-Philippe Bouchaud
Surface flow of granular material is investigated within a continuum approach in two dimensions. The dynamics is described by a non-linear coupling between the two `states' of the…
Experiments in randomly agitated granular assemblies close to the jamming transition
G. Caballero, A. Lindner, G. Ovarlez +3
We present here the preliminary results obtained for two experiments on randomly agitated granular assemblies using a novel way of shaking. First we discuss the transport propertie…
