高阶导数理论中带电黑洞的体-边界热力学

Bulk-Boundary Thermodynamics of Charged Black Holes in Higher Derivative Theory

Gurmeet Singh Punia

AI总结:

本文研究高阶导数引力耦合 U(1) 规范场中带电黑洞的体-边界热力学对应,提出需引入弦论参数 α' 的涨落作为记账工具以匹配两侧第一定律与 Smarr 关系,并揭示中心荷对边界热力学关系的修正。

摘要:

利用 AdS/CFT 对应,爱因斯坦-麦克斯韦理论中体与边界热力学之间的联系已经很好地建立起来。在一般高阶导数引力耦合 U(1) 规范场的背景下,我们考察了体与边界之间热力学第一定律的相似性,并在两侧给出了扩展相空间描述。与弦论参数 $α'$ 的不同幂次相关的高阶导数项来源于体超引力作用量中的一致截断。我们证明,必须在体热力学中引入 $α'$ 的涨落作为一种记账工具,才能使体的第一定律和 Smarr 关系与边界一侧相匹配。因此,欧拉关系和边界第一定律因加入两个中心荷($\mathtt{a}$,$\mathtt{c}$)而被修改。为支持我们的一般结论,我们考虑了 Gauss-Bonnet 引力中的黑洞以及一般的四导数理论。最后,我们考察了高阶导数修正黑洞的扩展相空间描述在体和边界两方面的表现。

英文摘要:

The connection between bulk and boundary thermodynamics in Einstein-Maxwell theory is well established using AdS/CFT correspondence. In the context of general higher derivative gravity coupled to a U(1) gauge field, we examine the resemblance of the first law of thermodynamics between bulk and boundary, followed by an extended phase space description on both sides. Higher derivative terms related to different powers of the string theory parameter $α'$ emerged from a consistent truncation in the bulk supergravity action. We demonstrate that one must include the fluctuation of $α'$ in the bulk thermodynamics as a bookkeeping tool to match the bulk first law and Smarr relation with the boundary side. Consequently, the Euler relation and the boundary first law are altered by adding two central charges ($\mathtt{a}$, $\mathtt{c}$). To support our general conclusion, we consider the black hole in Gauss-Bonnet gravity and the general four-derivative theory. Finally, we examine the bulk and boundary aspects of the extended phase space description for higher derivative corrected black holes.
