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…

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…

Equivalence of Noether charge and Hilbert action boundary term formulas for the black hole entropy in gravity theory

Wei Guo, Xiyao Guo, Mingfeng Li +2

By working with the covariant phase space formalism, we have shown that not only can the Hamiltonian conjugate to a Killing vector field be expressed as the sum of the associa…

Notes on solution phase space and BTZ black hole

Wei Guo

In this paper, we use the solution phase space approach based on the covariant phase space formalism to compute the conserved charges of the BTZ black hole, namely mass, angular mo…
