Anti-Evaporation of Schwarzschild-de Sitter Black Holes in gravity

arXiv:1301.2775 · doi:10.1088/0264-9381/30/12/125003

Abstract

We studied the anti-evaporation of degenerate Schwarzschild-de Sitter black hole (so-called Nariai space-time) in modified gravity. The analysis of perturbations of the Nariai black hole is done with the conclusion that anti-evaporation may occur in such a theory already on classical level. For several power-law gravities which may describe the inflation and/or dark energy eras we presented the theory parameters bounds for occurrence of anti-evaporation and conjectured creation of infinite number of horizons.
