Screened cluster expansions for partially ionized gases
A. Alastuey, V. Ballenegger, F. Cornu +1
We consider a partially ionized gas at thermal equilibrium, in the Saha regime. The system is described in terms of a quantum plasma of nuclei and electrons. In this framework, the…

Thermalization of a particle with dissipative collisions
Ph. A. Martin, J. Piasecki
One considers the motion of a test particle in an homogeneous fluid in equilibrium at temperature , undergoing dissipative collisions with the fluid particles. It is shown that…

Statistics of Mass Aggregation in a Large Self-Gravitating One-Dimensional Gas
J. C. Bonvin, Ph. A. Martin, J. Piasecki +1
We study at the microscopic level the dynamics of a one-dimensional gravitationally interacting sticky gas. Initially, N identical particles of mass m with uncorrelated, randomly d…
