介子-轴子黑洞的热力学

Thermodynamics Of dilaton-axion black holes

Tanwi Ghosh, Soumitra SenGupta

摘要:

考虑四维Einstein Maxwell理论的广义作用量与标量场和赝标量场的耦合,研究了在这种背景下渐近平坦黑洞解的热力学性质。证明了这类黑洞的Bekenstein-Hawking面积熵定律。从比热性质出发,证明了当电荷、质量和标量真空期望值等参数选择一定时,这类黑洞是稳定的。本文讨论了黑洞相变的可能性。

英文摘要:

Considering a generalised action for Einstein Maxwell theory in four dimensions coupled to scalar and pseudo-scalar fields, the thermodynamic properties of asymptotically flat black holes solutions in such a background are investigated. Bekenstein-Hawking area-entropy law is verified for these class of black holes. From the property of specific heat, it is shown that such black holes can be stable for certain choice of the parameters like charge, mass and the scalar vacuum expectation value. The possibility of a black hole phase transition is discussed in this context.
