弦论中带电黑洞的几何热力学

Geometrothermodynamics of a Charged Black Hole of String Theory

Alexis Larranaga, Sindy Mojica

摘要:

本文在几何热力学的新形式下,从弦论出发,对Gibbons-Maeda-Garfinkle-Horowitz-Strominger(GMGHS)带电黑洞的热力学进行了重新表述.平衡态空间的几何是弯曲的,但我们表明,热力学曲率不发散时,黑洞解成为一个裸奇点。这提供了一个反例,以传统的概念,一个曲率发散的信号发生的相变。

英文摘要:

The thermodynamics of the Gibbons-Maeda-Garfinkle-Horowitz-Strominger (GMGHS) charged black hole from string theory is reformulated within the context of the recently developed formalism of geometrothermodynamics. The geometry of the space of equilibrium states is curved, but we show that the thermodynamic curvature does not diverge when the black hole solution becomes a naked singularity. This provides a counterexample to the conventional notion that a thermodynamical curvature divergence signals the occurrence of a phase transition.
