广义相对论中费米子自引力系统的引力相变

Gravitational phase transition of self-gravitating systems of fermions in General Relativity

Giuseppe Alberti, Pierre-Henri Chavanis

摘要:

在广义相对论的框架下,推广了有限温度下的费米子引力相变模型。结果表明,当非简并费米子气体(对于$N < N_{OV}$,其中$N_{OV}$是Oppenheimer-Schottky极限)冷却到临界温度以下时,出现凝聚相,量子力学阻止了引力坍缩。相反,如果是$N > N_{OV}$,系统注定会坍缩成黑洞,因为不存在平衡态。

英文摘要:

The Thomas-Fermi model is extended at finite temperature, to describe the gravitational phase transition occurring in massive fermionic systems in a general-relativistic framework. It is shown that, when a nondegenerate fermionic gas (for $N < N_{OV}$, where $N_{OV}$ is the Oppenheimer-Volkoff limit) is cooled down below a critical temperature, a condensed phase emerges and the gravitational collapse is prevented by quantum mechanics. If $N > N_{OV}$, by contrast, the system is destined to collapse towards a Black Hole because no equilibrium states exist.
