Information conservation in de Sitter tunneling
Abstract In this paper, we consider the three most general cases of progressive de Sitter spacetime. The charged and magnetic particles tunnel into the magnetically charged Reissner–Nordström de Sitter black hole (the most general case of a static black hole), the Kerr–Newman–Kasuya de Sitter black...

| description | Abstract In this paper, we consider the three most general cases of progressive de Sitter spacetime. The charged and magnetic particles tunnel into the magnetically charged Reissner–Nordström de Sitter black hole (the most general case of a static black hole), the Kerr–Newman–Kasuya de Sitter black hole (the most general case of a rotating black hole), and Bardeen de Sitter black hole (black hole without singularities). We use Parikh–Wilczek method to calculate the radiation spectra of these black holes respectively, and find that they deviate from the pure thermal spectra, satisfying the unitary principle. Our results support the conservation of information and are generally true for all asymptotic de Sitter space-times. |
