Viscosity bound for anisotropic superfluids in higher derivative gravity
Arpan Bhattacharyya, Dibakar Roychowdhury
In the present paper, based on the principles of gauge/gravity duality we analytically compute the shear viscosity to entropy ratio corresponding to the superfluid phase in Einstei…
Attractive holographic -functions
Arpan Bhattacharyya, S. Shajidul Haque, Vishnu Jejjala +2
Using the attractor mechanism for extremal solutions in gauged supergravity, we construct a -function that interpolates between the central charges of theories at u…
On entanglement entropy functionals in higher derivative gravity theories
Arpan Bhattacharyya, Menika Sharma
In arXiv:1310.5713 and arXiv:1310.6659 a formula was proposed as the entanglement entropy functional for a general higher-derivative theory of gravity, whose lagrangian consists of…
Constraining gravity using entanglement in AdS/CFT
Shamik Banerjee, Arpan Bhattacharyya, Apratim Kaviraj +2
We investigate constraints imposed by entanglement on gravity in the context of holography. First, by demanding that relative entropy is positive and using the Ryu-Takayanagi entro…
