广义测不准关系与Reissner Nordstrom de Sitter黑洞熵

Abstract

Abstract:

Thinking of Klein Gorden equation in Reissner Nordstrom de Sitter spacetime, the entropy is calculated by the improved brick wall method due to the generalized uncertainty relation. The entropy bound of this s ystem not only includes the contribution of the black hole horizon, but also includes the contribution of the cosmological horizon. It is found that there is an internal relation between the event horizon and the entropy. It is also apparent that the cut off in brick wall model is something related to the quantum the ory of gravity.
