Effective temperature of vacuum and particles on the horizons

Аннотация

An approach has been proposed in which the evolution of horizons is determined by their effective temperature. Effective horizon lifetimes are evaluated for two spherically symmetric metrics. It has been obtained that the charge in the Reissner–Nordstro¨ m metric is lost much faster than its mass, and that Kottler’s metric vacuum in the early Universe may decay faster than Schwarzschild’s horizon evaporates. The results obtained may be of importance for black hole physics and cosmology.
