Complex Instantons and Charged Rotating Black Hole Pair Creation

Complex Instantons and Charged Rotating Black Hole Pair Creation

We consider the general process of pair-creation of charged rotating black holes. We find that instantons which describe this process are necessarily complex due to regularity requirements. However their associated probabilities are real, and fully consistent with the interpretation that the entropy of a charged rotating black hole is the logarithm of the number of its quantum states. Black hol...

Cosmological Pair Creation of Charged and Rotating Black Holes

In this paper, we investigate the creation of charged and rotating black hole pairs in a background with a positive cosmological constant. Instantons to describe this situation are constructed from the Kerr-Newmann deSitter solution to the Einstein-Maxwell equations and the actions of these instantons are calculated in order to estimate pair creation rates and the entropy of the created spaceti...

Wormholes and Black Hole Pair Creation

We analyze the possibility of black holes pair creation induced by three dimensional wormholes. Although this spacetime configuration is nowadays hard to suppose, it can be very important in the early universe, when the wormhole spacetime foam representation can be meaningful. We compare our approach with the no-boundary prescription of Hartle-Hawking. PACS numbers: 04.60, 04.70.Dy, 98.80Hw Typ...
