Winstanley, E. orcid.org/0000-0001-8964-8142 (2001) Classical super-radiance in Kerr-Newman-anti-de Sitter black holes. Physical Review D, 64 (10). 104010. ISSN 0556-2821
Abstract
We study in detail the modes of a classical scalar field on a Kerr–Newman–anti-de Sitter (KN-AdS) black hole. We construct sets of basis modes appropriate to the two possible boundary conditions (“reflective” and “transparent”) at timelike infinity, and consider whether super-radiance is possible. If we employ “reflective” boundary conditions, all modes are non-super-radiant. On the other hand, for “transparent” boundary conditions, the presence of super-radiance depends on our definition of positive frequency. For those KN-AdS black holes having a globally time-like Killing vector, the natural choice of positive frequency leads to no super-radiance. For other KN-AdS black holes, there is a choice of positive frequency which gives no super-radiance, but for other choices there will, in general, be super-radiance.
