Thermodynamics of nonsingular spherically symmetric black hole

摘要

Black hole whose singularity is replaced by a de Sitter-like core could arise as a result of vacuum polarization effects at the scale of symmetry restoration. De Sitter-Schwarzschild black hole has two horizons. Global structure of de Sitter-Schwarzschild spacetime contains, in place of both future and past Schwarzschild singularities, an infinite sequence of new structures: asymptotically flat regions, black and white holes, and regular de Sitter-like cores.
