Entropy of continuous mixtures and the measure problem
P. Maynar, E. Trizac
In its continuous version, the entropy functional measuring the information content of a given probability density may be plagued by a "measure" problem that results from improper…
Energy fluctuations in a randomly driven granular fluid
M. I. Garcia de Soria, P. Maynar, E. Trizac
We study the behavior of the energy fluctuations in the stationary state of a uniformly heated granular gas. The equation for the one-time two-particle correlation function is deri…
Brownian motion under annihilation dynamics
M. I. Garcia de Soria, P. Maynar, E. Trizac
The behavior of a heavy tagged intruder immersed in a bath of particles evolving under ballistic annihilation dynamics is investigated. The Fokker-Planck equation for this system i…
Breakdown of fluctuation-dissipation relations in granular gases
J. J. Brey, M. I. Garcia de Soria, P. Maynar
A numerical molecular dynamics experiment measuring the two-time correlation function of the transversal velocity field in the homogeneous cooling state of a granular gas is report…
Dynamics of Annihilation II: Fluctuations of Global Quantities
P. Maynar, M. I. Garcia de Soria, G. Schehr +2
We develop a theory for fluctuations and correlations in a gas evolving under ballistic annihilation dynamics. Starting from the hierarchy of equations governing the evolution of m…
Dynamics of Annihilation I : Linearized Boltzmann Equation and Hydrodynamics
M. I. Garcia de Soria, P. Maynar, G. Schehr +2
We study the non-equilibrium statistical mechanics of a system of freely moving particles, in which binary encounters lead either to an elastic collision or to the disappearance of…
