Kinetic theory of two-dimensional point vortices and fluctuation-dissipation theorem
Pierre-Henri Chavanis
We complete the kinetic theory of two-dimensional (2D) point vortices initiated in previous works. We use a simpler and more physical formalism. We consider a system of 2D point vo…
Maximum mass of relativistic self-gravitating Bose-Einstein condensates with repulsive or attractive self-interaction
Pierre-Henri Chavanis
We derive an approximate analytical expression of the maximum mass of relativistic self-gravitating Bose-Einstein condensates with repulsive or attractive self-interaction.…
Long-term relaxation of self-gravitating systems
Mathieu Roule, Jean-Baptiste Fouvry, Christophe Pichon +1
We investigate the long-term relaxation of one-dimensional () self-gravitating systems, using both kinetic theory and -body simulations. We consider thermal and Plummer eq…
A new logotropic model based on a complex scalar field with a logarithmic potential
Pierre-Henri Chavanis
We introduce a new logotropic model based on a complex scalar field with a logarithmic potential that unifies dark matter and dark energy. The scalar field satisfies a nonlinear wa…
Predictions from the logotropic model: the universal surface density of dark matter halos and the present proportion of dark matter and dark energy
Pierre-Henri Chavanis
The logotropic model [P.H. Chavanis, Eur. Phys. J. Plus {\bf 130}, 130 (2015)] may be an interesting alternative to the CDM model. It is able to account for the present accelera…
