Reconstructing gravity from generalized entropies: exact Lagrangians
Ankit Anand, Sahil Devdutt, Kimet Jusufi +2
Generalized horizon entropies are widely used as theoretical modifications of the Bekenstein-Hawking area law, but through the Wald construction they may also encode modifications…
Non-Minimally Coupled Scalar Field, Area Quantization and Black Hole Entropy
Sahil Devdutt, Akriti Garg, Ayan Chatterjee
The enumeration of black hole entropy in candidate theories of quantum gravity utilises the quantum properties of microstates residing on the black hole horizon. For example, in Lo…
Effective matter sectors from modified entropies
Ankit Anand, Sahil Devdutt, Kimet Jusufi +1
We present a general formalism linking modified entropy functions directly to a modified spacetime metric and, subsequently, to an effective matter sector of entropic origin. In pa…
Laws of black hole mechanics in the Einstein-Gauss-Bonnet theory
Ayan Chatterjee, Sahil Devdutt, Avirup Ghosh
We extend the isolated horizon formalism to include rotating black holes arising in five dimensional Einstein-Gauss-Bonnet (EGB) theory of gravity, and derive the laws of black hol…
