Creation of Kerr-de Sitter Black Hole in All Dimensions
Zhong Chao Wu
We discuss the quantum creation scenario of a Kerr-de Sitter black hole in all dimensions. We show that its relative creation probability is the exponential to the entropy of the b…
No-boundary Codimension-two Braneworld
Zhong Chao Wu
The quantum creation probability and entropy of a 2-codimensional braneworld are calculated in the framework of no-boundary universe. The entropy can take an arbitrarily large valu…
Dimensionality in the Freund-Rubin Cosmology
Zhong Chao Wu
In the dimensional Freund-Rubin model with an antisymmetric tensor field of rank , the dimension of the external spacetime we live in must be . This result is…
Quantum Kaluza-Klein Cosmologies (V)
Zhong Chao Wu
In the No-boundary Universe with supergravity, under the Kaluza-Klein ansatz, the only seed instanton for the universe creation is a s…
The Topological Origin of Black Hole Entropy
Zhong Chao Wu
In gravitational thermodynamics, the origin of a black hole's entropy is the topology of its instanton or constrained instanton. We prove that the entropy of an arbitrary nonrotati…
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…
