We examine the Kerr/CFT correspondence in Einstein gravity extended with quadratic curvature invariants. We consider two explicit examples in four and five dimensions and compute the central charges of the asymptotic symmetry algebras of the near horizon geometries, using the improved version of the BBC formalism that encompasses the information of the Lagrangian. We find that the resulting Cardy entropy differs from the Wald entropy, caused by the Riemann-squared RμνρσRμνρσ term.

A preprint version of the article is available at ArXiv.

关于高导数重力中 Kerr/CFT 和 Wald 熵差异的说明

我们研究了用二次曲率不变量扩展的爱因斯坦引力中的 Kerr/CFT 对应关系。我们考虑四个和五个维度的两个显式示例,并使用包含拉格朗日信息的 BBC 形式主义的改进版本计算近视界几何的渐近对称代数的中心电荷。我们发现由此产生的 Cardy 熵与 Wald 熵不同,这是由黎曼平方R μνρσ R μνρσ项引起的。
