Taub-NUT和Taub-Bolt热力学相结构的扩展

The Extended Thermodynamic Phase Structure of Taub-NUT and Taub-Bolt

Clifford V. Johnson

摘要:

我们研究了四维局部反德西特时空中的Taub-NUT和Taub-Bolt几何的广义引力热力学,其中宇宙学常数被视为动力学压力.注意在(p,T)平面,其中有一个线的第一级相变从原点延伸的相结构。我们主张在负比热区的不稳定物理的动力学解释。对应于一个动态Taub-NUT/螺栓系统的变形也进行了探讨,和变形的效果上的相图的特点。

英文摘要:

We study aspects of the extended gravitational thermodynamics for the Taub-NUT and Taub-Bolt geometries in four dimensional locally anti-de Sitter spacetime, where the cosmological constant is treated as a dynamical pressure. Attention is paid to the phase structure in the (p,T) plane, which has a line of first order phase transitions extending from the origin. We argue for a dynamical interpretation of the unstable physics in the negative specific heat region. A deformation corresponding to a dyonic Taub-NUT/Bolt system is also explored, and the effect of the deformation on the phase diagram is characterised.
