摘要:

研究了反德西特宇宙背景下一类$(n+1)$维带电粒子在黑洞上的热力学不稳定性。利用Brown和York的减法计算了黑洞上AdS粒子的准定域质量。我们发现一个Smarr型的公式,并进行稳定性分析的正则系综和揭示的热稳定性的解决方案的效果的介子场。我们的研究表明,对于小的$α$,系统的解是热稳定的,而对于大的$α$,系统有一个不稳定的相,其中$α$是介子和物质场之间的耦合常数.

英文摘要:

We study thermodynamic instability of a class of $(n+1)$-dimensional charged dilaton black holes in the background of anti-de Sitter universe. We calculate the quasilocal mass of the AdS dilaton black hole through the use of the subtraction method of Brown and York. We find a Smarr-type formula and perform a stability analysis in the canonical ensemble and disclose the effect of the dilaton field on the thermal stability of the solutions. Our study shows that the solutions are thermally stable for small $α$, while for large $α$ the system has an unstable phase, where $α$ is a coupling constant between the dilaton and matter field.
