From normal diffusion to superdiffusion of energy in the evanescent flip noise limit
Cédric Bernardin, Patricia Gonçalves, Milton Jara +2
We consider a harmonic chain perturbed by an energy conserving noise depending on a parameter . When is of order one, the energy diffuses according to the standard heat equa…
Microscopic derivation of an adiabatic thermodynamic transformation
Stefano Olla, Marielle Simon
We obtain macroscopic adiabatic thermodynamic transformations by space-time scalings of a microscopic Hamiltonian dynamics subject to random collisions with the environment. The mi…
A parameter identification problem in stochastic homogenization
F. Legoll, W. Minvielle, A. Obliger +1
In porous media physics, calibrating model parameters through experiments is a challenge. This process is plagued with errors that come from modelling, measurement and computation…
Equilibrium fluctuations for the disordered harmonic chain perturbed by an energy conserving noise
Clément Erignoux, Marielle Simon
We investigate the macroscopic behavior of the disordered harmonic chain of oscillators, through energy diffusion. The Hamiltonian dynamics of the system is perturbed by a degenera…
