Energy Balance of a Bose Gas in Curved Spacetime
Tonatiuh Matos, Ana Avilez, Tula Bernal +1
The paper derives a general‑relativistic version of the Gross‑Pitaevskii equation using a 3+1 ADM foliation and obtains an energy balance equation for a Bose‑Einstein condensate in…
Energy Balance of a Boson Gas at Zero Temperature in Curved Spacetime
Jorge Meza-DomÃnguez, Tonatiuh Matos, Pierre-Henri Chavanis
We develop a comprehensive thermodynamic description for a zero-temperature boson gas in curved spacetime, integrating energy conservation with information-theoretic principles. Us…
Thermal activation rate of dilute axion stars close to the maximum mass
Pierre-Henri Chavanis
We compute the thermal activation rate of metastable self-gravitating Bose-Einstein condensates with attractive self-interaction (e.g., dilute axion stars) by using the instanton t…
Polytropes, logotropes, the universal value of the surface density of dark matter halos, and the value of the cosmological constant
Pierre-Henri Chavanis
We discuss the connection between logotropes and polytropes in astrophysics and cosmology. The logotropic equation of state may be seen as a degenerate form of th…
Thermodynamics of self-gravitating fermions as a robust theory for dark matter halos: Stability analysis applied to the Milky Way
A. Krut, C. R. Argüelles, P. -H. Chavanis
We present a framework for dark matter (DM) halo formation based on a kinetic theory of self-gravitating fermions together with a solid connection to thermodynamics. Based on maxim…
Kinetic theory of two-dimensional point vortices at order and
Jean-Baptiste Fouvry, Pierre-Henri Chavanis
We investigate the long-term relaxation of a distribution of point vortices in two-dimensional hydrodynamics. To focus on the regime of weak collective amplification, we embed…
