Stationary state of a heated granular gas: fate of the usual H-functional
Ioana Bena, Francois Coppex, Michel Droz +3
We consider the characterization of the nonequilibrium stationary state of a randomly-driven granular gas in terms of an entropy-production based variational formulation. Enforcing…
Fluctuations of power injection in randomly driven granular gases
P. Visco, A. Puglisi, A. Barrat +2
We investigate the large deviation function pi(w) for the fluctuations of the power W(t)=w t, integrated over a time t, injected by a homogeneous random driving into a granular gas…
Fluctuations of internal energy flow in a vibrated granular gas
A. Puglisi, P. Visco, A. Barrat +2
The non-equilibrium fluctuations of power flux in a fluidized granular media have been recently measured in an experiment [Phys. Rev. Lett. 92, 164301, 2004], which was announced t…
Maxwell and very hard particle models for probabilistic ballistic annihilation: hydrodynamic description
Francois Coppex, Michel Droz, Emmanuel Trizac
The hydrodynamic description of probabilistic ballistic annihilation, for which no conservation laws hold, is an intricate problem with hard sphere-like dynamics for which no exact…
