Work fluctuation theorems and free energy from kinetic theory
J. Javier Brey, M. J. Ruiz-Montero, Alvaro Dominguez
The formulation of the First and Second Principles of thermodynamics for a particle in contact with a heat bath and submitted to an external force is analyzed, by means of the Bolt…
Anomalous self-diffusion in a freely evolving granular gas near the shearing instability
J. Javier Brey, Maria J. Ruiz-Montero
The self-diffusion coefficient of a granular gas in the homogeneous cooling state is analyzed near the shearing instability. Using mode-coupling theory, it is shown that the coeffi…
Power-law decay of the velocity autocorrelation function of a granular fluid in the homogeneous cooling state
J. Javier Brey, M. J. Ruiz-Montero
The hydrodynamic part of the velocity autocorrelation function of a granular fluid in the homogeneous cooling state has been calculated by using mode-coupling theory for a finite s…
Exact non-equilibrium solutions of the Boltzmann equation under a time-dependent external force
D. Guéry-Odelin, J. G. Muga, M. J. Ruiz-Montero +1
We construct a novel class of exact solutions to the Boltzmann equation, in both its classical and quantum formulation, for arbitrary collision laws. When the system is subjected t…
Uniform self-diffusion in a granular gas
J. Javier Brey, M. J. Ruiz-Montero
A granular gas composed of inelastic hard spheres or disks in the homogeneous cooling state is considered. Some of the particles are labeled and their number density exhibits a tim…
Steady self-diffusion in classical gases
J. Javier Brey, M. J. Ruiz-Montero
A steady self-diffusion process in a gas of hard spheres at equilibrium is analyzed. The system exhibits a constant gradient of labeled particles. Neither the concentration of thes…
