On generalized gravitational entropy, squashed cones and holography
Arpan Bhattacharyya, Menika Sharma, Aninda Sinha
We consider generalized gravitational entropy in various higher derivative theories of gravity dual to four dimensional CFTs using the recently proposed regularization of squashed…
Entanglement entropy in higher derivative holography
Arpan Bhattacharyya, Apratim Kaviraj, Aninda Sinha
We consider holographic entanglement entropy in higher derivative gravity theories. Recently Lewkowycz and Maldacena arXiv:1304.4926 have provided a method to derive the equations…
Entanglement entropy from surface terms in general relativity
Arpan Bhattacharyya, Aninda Sinha
Entanglement entropy in local quantum field theories is typically ultraviolet divergent due to short distance effects in the neighbourhood of the entangling region. In the context…
Entanglement entropy from the holographic stress tensor
Arpan Bhattacharyya, Aninda Sinha
We consider entanglement entropy in the context of gauge/gravity duality for conformal field theories in even dimensions. The holographic prescription due to Ryu and Takayanagi (RT…
