Microreversibility, nonequilibrium current fluctuations, and response theory
Maximilien Barbier, Pierre Gaspard
Microreversibility rules the fluctuations of the currents flowing across open systems in nonequilibrium (or equilibrium) steady states. As a consequence, the statistical cumulants…
Microscopic origin of self-similarity in granular blast waves
Matthieu Barbier, Dario Villamaina, Emmanuel Trizac
The self-similar expansion of a blast wave, well-studied in air, has peculiar counterparts in dense and dissipative media such as granular gases. Recent results have shown that, wh…
Blast dynamics in a dissipative gas
Matthieu Barbier, Dario Villamaina, Emmanuel Trizac
The blast caused by an intense explosion has been extensively studied in conservative fluids, where the Taylor-von Neumann-Sedov hydrodynamic solution is a prototypical example of…
Polydispersity and optimal relaxation in the hard sphere fluid
Matthieu Barbier, Emmanuel Trizac
We consider the mass heterogeneity in a gas of polydisperse hard particles as a key to optimizing a dynamical property: the kinetic relaxation rate. Using the framework of the Bolt…
Field induced stationary state for an accelerated tracer in a bath
Matthieu Barbier, Emmanuel Trizac
Our interest goes to the behavior of a tracer particle, accelerated by a constant and uniform external field, when the energy injected by the field is redistributed through collisi…
