熵泛函的欧氏分析

Euclidean analysis of the entropy functional formalism

Oscar J. C. Dias, Pedro J. Silva

摘要:

吸引子机制意味着超对称黑洞的近视界解只定义在保守的费用,因此是独立的渐近模。仅从近视界几何开始,Sen的熵泛函形式主义通过Legendre变换计算极端黑洞的熵,其中电场被定义为电荷的共轭变量。然而,传统的欧几里德方法需要完整的几何知识来计算黑洞的热力学量。我们建立了熵泛函形式主义和零温度下的标准欧几里得形式主义之间的联系。我们发现,森的熵函数'f'(壳)匹配的零温度极限的欧几里德行动。此外,森的近地平线角和电场同意的化学势,从零温度极限的欧几里德形式主义。

英文摘要:

The attractor mechanism implies that the supersymmetric black hole near horizon solution is defined only in terms of the conserved charges and is therefore independent of asymptotic moduli. Starting only with the near horizon geometry, Sen's entropy functional formalism computes the entropy of an extreme black hole by means of a Legendre transformation where the electric fields are defined as conjugated variables to the electric charges. However, traditional Euclidean methods require the knowledge of the full geometry to compute the black hole thermodynamic quantities. We establish the connection between the entropy functional formalism and the standard Euclidean formalism taken at zero temperature. We find that Sen's entropy function 'f' (on-shell) matches the zero temperature limit of the Euclidean action. Moreover, Sen's near horizon angular and electric fields agree with the chemical potentials that are defined from the zero-temperature limit of the Euclidean formalism.
