Reproducing the integer count of black hole micro-states from the gravitational path integral
is an important problem in quantum gravity. In this paper, we show that, by using …

A bstract Understanding how to prepare and count black hole micro-states by using the
gravitational path integral is one of the most important problems in quantum gravity …

Logarithmic corrections to the extremal black hole entropy can be computed purely in terms
of the low energy data—the spectrum of massless fields and their interaction. The demand of …

We consider degrees of freedom for a quantum de Sitter spacetime. The problem is studied
from both a Lorentzian and a Euclidean perspective. From a Lorentzian perspective, we …

A bstract We compute logarithmic corrections to the entropy of supersymmetric extremal
black holes in\(\mathcal {N}={4}\) and\(\mathcal {N}={8}\) supersymmetric string theories and …

We evaluate the one loop determinant of matter multiplet fields of\(\mathcal {N}= 4\)
supergravity in the near horizon geometry of quarter BPS black holes, and use it to calculate …

We compute logarithmic corrections to the entropy of rotating extremal black holes using
quantum entropy function ie Euclidean quantum gravity approach. Our analysis includes five …

A bstract Non-perturbative quantum corrections to supersymmetric black hole entropy often
involve nontrivial number-theoretic phases called Kloosterman sums. We show how these …

A bstract We consider the AdS 2/CFT 1 holographic correspondence near the horizon of big
four-dimensional black holes preserving four supersymmetries in toroidally compactified …
