Gravitational collapse of a Brownian gas
C. Sire, P. H. Chavanis
We investigate a model describing the dynamics of a gas of self-gravitating Brownian particles. This model can also have applications for the chemotaxis of bacterial populations. W…
Generalized kinetic equations and effective thermodynamics
Pierre-Henri Chavanis
We introduce a new class of nonlocal kinetic equations and nonlocal Fokker-Planck equations associated with an effective generalized thermodynamical formalism. These equations have…
Thermodynamics of MHD flows with axial symmetry
Nicolas Leprovost, Pierre-Henri Chavanis, Berengere Dubrulle
We present strategies based upon extremization principles, in the case of the axisymmetric equations of magnetohydrodynamics (MHD). We study the equilibrium shape by using a minimu…
Statistical mechanics of two-dimensional vortices and stellar systems
P. H. Chavanis
The formation of large-scale vortices is an intriguing phenomenon in two-dimensional turbulence. Such organization is observed in large-scale oceanic or atmospheric flows, and can…
Statistical mechanics of violent relaxation in stellar systems
P. H. Chavanis
We discuss the statistical mechanics of violent relaxation in stellar systems following the pioneering work of Lynden-Bell (1967). The solutions of the gravitational Vlasov-Poisson…
The self-gravitating Fermi gas
P. H. Chavanis
We discuss the nature of phase transitions in the self-gravitating Fermi gas at non-zero temperature. This study can be relevant for massive neutrinos in Dark Matter models and for…
