Can Black Hole be Created at the Birth of the Universe?
Zhong Chao Wu
We study the quantum creation of black hole pairs in the (anti-)de Sitter space background. These black hole pairs in the Kerr-Newman family are created from constrained instantons…

Entropy of a Black Hole with Distinct Surface Gravities
Zhong Chao Wu
In gravitational thermodynamics, the entropy of a black hole with distinct surface gravities can be evaluated in a microcanonical ensemble. At the level, the entropy becomes…

Quantum Creation of BTZ Black Hole
Zhong Chao Wu
The constrained instanton method is used to study quantum creation of a black hole. It is found that the relative creation probability is the exponential of the negative sum…
