Abstract

Albeit great deal of work, we are still far from ‘the’ quantum theory of gravity. Yet, the past few decades have seen a shift in the way the problem is viewed. It is by now clear that even though Quantum General Relativity is perturbatively non-renormalizable, it is a well-behaved low-energy effective theory. In this talk, I will discuss the EFT treatment of quantum gravity and some recent progress in “infrared quantum gravity”. As an application, I will focus on computing the partition function of Euclidean quantum gravity utilizing the EFT techniques. I will re-investigate the question about the thermal stability of Schwarzschild black hole, when one takes into account the quantum corrections due to massless fluctuations. Moreover, the effective theory can tell us a great deal about the UV as well. I will show how one can obtain constraints on the UV completion of quantum gravity by a careful study of the logarithmic correction to Bekenstein-Hawking entropy.
