Gravitational Phase Transition of Fermionic Matter in a General-relativistic Framework |
|
Abstract |
The Thomas-Fermi model at finite temperature is extended to describe a system of self-gravitating massive fermions in a general-relativistic framework. The existence and properties of the gravitational phase transition, in both the canonical and microcanonical ensembles, are investigated numerically. It is shown that, in the canonical ensemble, when a non-degenerate fermionic gas is cooled below a critical temperature, a condensed phase emerges, consisting of quasi-degenerate fermion stars. In the microcanonical ensemble, similarly, a condensed phase emerges when the energy of the system is below a critical value. |
