Anomaly freedom in perturbative loop quantum gravity
Martin Bojowald, Golam Mortuza Hossain, Mikhail Kagan +1
A fully consistent linear perturbation theory for cosmology is derived in the presence of quantum corrections as they are suggested by properties of inverse volume operators in loo…
Quantum gravitational corrections to the stress-energy tensor around the rotating BTZ black hole
Dawood A. Kothawala, S. Shankaranarayanan, L. Sriramkumar
Modes emerging out of a collapsing black hole are red-shifted to such an extent that Hawking radiation at future null infinity consists of modes that have energies beyond the Planc…
Power-law corrections to black-hole entropy via entanglement
Saurya Das, S. Shankaranarayanan, Sourav Sur
We consider the entanglement between quantum field degrees of freedom inside and outside the horizon as a plausible source of black-hole entropy. We examine possible deviations of…
Sub-leading contributions to the black hole entropy in the brick wall approach
Sudipta Sarkar, S. Shankaranarayanan, L. Sriramkumar
[Abridged] We compute the canonical entropy of a quantum scalar field around static and spherically symmetric black holes through the brick wall approach at the higher orders (in f…
Where are the degrees of freedom responsible for black hole entropy?
Saurya Das, S. Shankaranarayanan, Sourav Sur
Considering the entanglement between quantum field degrees of freedom inside and outside the horizon as a plausible source of black hole entropy, we address the question: {\it wher…
Power-law corrections to entanglement entropy of horizons
Saurya Das, S. Shankaranarayanan, Sourav Sur
We re-examine the idea that the origin of black-hole entropy may lie in the entanglement of quantum fields between inside and outside of the horizon. Motivated by the observation t…
