非线性电磁场作用下的黑洞热力学

Black hole thermodynamics in the presence of nonlinear electromagnetic fields

Ana Bokulić, Tajron Jurić, Ivica Smolić

摘要:

由于黑洞与高能带电物质之间的相互作用受到量子修正,黑洞力学的基本定律必须仔细地重新推导。使用协变相空间形式主义,我们概括了黑洞力学的第一定律,“平衡态“和“物理过程”的版本,在存在的非线性电动力学领域,定义的拉格朗日依赖于两个二次电磁不变量,$F_{ab}F^{ab}$和$F_{ab}\,{\star F}^{ab}$。这个定律的推导需要对拉格朗日参数进行特殊的处理,类似于将宇宙学常数嵌入热力学背景。此外,我们讨论了能量条件的有效性,黑洞电动力学第零定律的几个补充证明和最近推广的Smarr公式的某些方面,它的(非)线性和第一定律的关系。

英文摘要:

As the interaction between the black holes and highly energetic infalling charged matter receives quantum corrections, the basic laws of black hole mechanics have to be carefully rederived. Using the covariant phase space formalism, we generalize the first law of black hole mechanics, both "equilibrium state" and "physical process" versions, in the presence of nonlinear electrodynamics fields, defined by Lagrangians depending on both quadratic electromagnetic invariants, $F_{ab}F^{ab}$ and $F_{ab}\,{\star F}^{ab}$. Derivation of this law demands a specific treatment of the Lagrangian parameters, similar to embedding of the cosmological constant into thermodynamic context. Furthermore, we discuss the validity of energy conditions, several complementing proofs of the zeroth law of black hole electrodynamics and some aspects of the recently generalized Smarr formula, its (non-)linearity and relation to the first law.
