Thermodynamics remains valid only for charged dS black holes.

Abstract

In this paper, a charged black hole in de Sitter space considered and logarithmic corrected entropy used to study thermodynamics. Logarithmic corrections of entropy comes from thermal fluctuations which play role of quantum loop corrections. In that case we are able to study the effect of quantum loop on the black hole thermodynamics and statistics. As black hole is a gravitational object, so it helps to obtain some information about the quantum gravity. The first and second laws of thermodynamics investigated for logarithmic corrected case and find that is only valid for the charged dS black hole. We show that the black hole phase transition disappear in presence of logarithmic correction.
