Thermodynamics of regular black hole with de Sitter core

Abstract

In this paper, we explore thermodynamics, thermal stability, effects of logarithmic corrections on thermodynamic quantities and phase transitions of spherically symmetric regular black hole with the de Sitter core. We first calculate the expressions for Hawking temperature as well as heat capacity and investigate its thermal stability. We also discuss the effects of logarithmic corrections on thermodynamical quantities such as pressure, Gibbs–Helmholtz free energy, internal energy and enthalpy of the system. Finally, we analyze the behavior of Hawking temperature as well as specific heat capacity of the regular black hole versus entropy for different values of the de Sitter parameter [Formula: see text]. It is found that Hawking temperature changes its phase from positive to negative and heat capacity changes its phase from negative to positive for large values of [Formula: see text].
