Abstract

In this paper, we discuss remnants and quantum gravity effects on thermodynamics of new kind of regular black hole known as Culetu black hole. The black hole results in coupling of gravity to non linear electrodynamic source. We first derive various thermodynamic quantities of interest. We then discuss in detail the existence and stability of remnants. The stability of remnants is analyzed in presence of thermal fluctuations and we observe that thermal fluctuations tend to increase the entropy at the horizon radius which is exactly the remnant radius. We then investigate non perturbative quantum gravity effects on the thermodynamics of Culetu black hole up to leading order terms.
