The rich behavior of the Boltzmann equation for dissipative gases
M. H. Ernst, E. Trizac, A. Barrat
Within the framework of the homogeneous non-linear Boltzmann equation, we present a new analytic method, without the intrinsic limitations of existing methods, for obtaining asympt…
Injected power and entropy flow in a heated granular gas
P. Visco, A. Puglisi, A. Barrat +2
Our interest goes to the power injected in a heated granular gas and to the possibility to interpret it in terms of entropy flow. We numerically determine the distribution of the i…
What is the temperature of a granular medium?
A. Baldassarri, A. Barrat, G. D'Anna +3
In this paper we discuss whether thermodynamical concepts and in particular the notion of temperature could be relevant for the dynamics of granular systems. We briefly review how…
Granular gases: dynamics and collective effects
Alain Barrat, Emmanuel Trizac, Matthieu H. Ernst
We present a biased review of some of the most "spectacular" effects appearing in the dynamics of granular gases where the dissipative nature of the collisions leads to a rich phen…
Extreme events driven glassy behaviour in granular media
G. D'Anna, P. Mayor, G. Gremaud +2
Motivated by recent experiments on the approach to jamming of a weakly forced granular medium using an immersed torsion oscillator [Nature 413 (2001) 407], we propose a simple mode…
Random inelasticity and velocity fluctuations in a driven granular gas
Alain Barrat, Emmanuel Trizac
We analyze the deviations from Maxwell-Boltzmann statistics found in recent experiments studying velocity distributions in two-dimensional granular gases driven into a non-equilibr…
