Quantum Nonthermal Radiation of Kerr-anti-de Sitter Black Holes

摘要

We examine the properties of Quantum nonthermal radiation of a Kerr-anti-deSitter (KAdS) black holes. Assuming that a crossing of the positive andnegative Dirac energy levels occurs in a region near the event horizon of thehole, and spontaneous quantum nonthermal radiation takes place in the overlapregion. We solve the biquadratic equation governing the location of the eventhorizon of the KAdS black holes and present closed analytic expression for theradii of the horizons.
