Coarsening dynamics of zero-range processes
C Godreche, J M Drouffe
We consider a class of zero-range processes exhibiting a condensation transition in the stationary state, with a critical single-site distribution decaying faster than a power law.…
The Kovacs effect in model glasses
E. M. Bertin, J. -P. Bouchaud, J. -M. Drouffe +1
We discuss the `memory effect' discovered in the 60's by Kovacs in temperature shift experiments on glassy polymers, where the volume (or energy) displays a non monotonous time beh…
Temporal Correlations and Persistence in the Kinetic Ising Model: the Role of Temperature
J. -M. Drouffe, C. Godreche
We study the statistical properties of the sum , that is the difference of time spent positive or negative by the spin , located at a given site…
Stationary definition of persistence for finite temperature phase ordering
J-M Drouffe, C Godreche
For the two dimensional kinetic Ising model at finite temperature, the local mean magnetisation $M_t=t^{-1}\int_{0}^tσ(t')\d t'$, simply related to the fraction of time spent by a…
Coarsening and persistence in a class of stochastic processes interpolating between the Ising and voter models
J-M Drouffe, C Godreche
We study the dynamics of a class of two dimensional stochastic processes, depending on two parameters, which may be interpreted as two different temperatures, respectively associat…
A simple stochastic model for the dynamics of condensation
J-M Drouffe, C Godreche, F Camia
We consider the dynamics of a model introduced recently by Bialas, Burda and Johnston. At equilibrium the model exhibits a transition between a fluid and a condensed phase. For lon…
