The identification between the bulk and boundary conserved quantities

Gerui Chen, Zien Gao, Xin Lan +2

By using Wald formalism, we show that the identification between the bulk and boundary conserved quantities induced by the perturbation of generic non-electromagnetic matter field…

Black hole thermodynamics is around the corner

Gerui Chen, Wei Guo, Xin Lan +2

We propose to work on the Euclidean black hole solution with a corner rather than with the prevalent conical singularity. As a result, we find that the Wald formula for black hole…

Quadratic curvature corrections to 5-dimensional Kerr-AdS black hole thermodynamics by background subtraction method

Gerui Chen, Xiyao Guo, Xin Lan +2

We justify the applicability of the background subtraction method to both Einstein's gravity and its higher derivative corrections in 5-dimensional asymptotically AdS spacetimes, w…

Higher derivative corrections to Kerr-AdS black hole thermodynamics

Wei Guo, Xiyao Guo, Xin Lan +2

Instead of the much more involved covariant counterterm method, we apply the well justified background subtraction method to calculate the first order corrections to Kerr-AdS black…

Background subtraction method is not only much simpler, but also as applicable as covariant counterterm method

Wei Guo, Xiyao Guo, Xin Lan +2

As the criterion for the applicability of the background subtraction method, not only the finiteness condition of the resulting Hamiltonian but also the condition for the validity…
