Corrected black hole thermodynamics in Damour-Ruffini's method with generalized uncertainty principle

摘要

Recently, some approaches to quantum gravity indicate that a minimal measurable length l(p) similar to 10(-35) should be considered, a direct implication of the minimal measurable length is the generalized uncertainty principle (GUP). Taking the effect of GUP into account, Hawking radiation of massless scalar particles from a Schwarzschild black hole is investigated by the use of Damour-Ruffini's method. The original Klein-Gordon equation is modified. It is obtained that the corrected Hawking temperature is related to the energy of emitting particles. Some discussions appear in the last section.
