Large Black Holes in an environment
Taniya Mandal, Arunabha Saha
We construct dynamical black hole solutions to Einstein Equations in presence of matter in the large limit. The matter stress tensors that we consider are weak in the sense tha…
General Theory of Large D Membranes Consistent with Second Law of Thermodynamics
Arunabha Saha
We write down the most general membrane equations dual to black holes for a general class of gravity theories, up to sub-leading order in in large limit. We derive a "min…
Large D membrane for Higher Derivative Gravity and Black Hole Second Law
Yogesh Dandekar, Arunabha Saha
We derive the effective equations of the membranes dual to black holes in a particular theory of higher derivative gravity namely Einstein-Gauss-Bonnet (EGB) gravity at sub-leading…
The large membrane paradigm for general four-derivative theory of gravity with a cosmological constant
Aditya Kar, Taniya Mandal, Arunabha Saha
We find the membrane equations which describe the leading order in dynamics of black holes in the limit for the most general four-derivative theory of gr…
The large D Membrane Paradigm For Einstein-Gauss-Bonnet Gravity
Arunabha Saha
We find the equations of motion of membranes dual to the black holes in Einstein-Gauss-Bonnet (EGB) gravity to leading order in 1/D in the large D regime. We also find the metric s…
An Action for and Hydrodynamics from the improved Large D membrane
Yogesh Dandekar, Suman Kundu, Subhajit Mazumdar +3
It has recently been demonstrated that black hole dynamics at large D is dual to the motion of a probe membrane propagating in the background of a spacetime that solves Einstein's…
Unstable `black branes' from scaled membranes at large
Yogesh Dandekar, Subhajit Mazumdar, Shiraz Minwalla +1
It has recently been demonstrated that the dynamics of black holes at large can be recast as a set of non gravitational membrane equations. These membrane equations admit a sim…
The large D black hole Membrane Paradigm at first subleading order
Yogesh Dandekar, Anandita De, Subhajit Mazumdar +2
In the large D limit, and under certain circumstances, it has recently been demonstrated that black hole dynamics in asymptotically flat spacetime reduces to the dynamics of a non…
A membrane paradigm at large D
Sayantani Bhattacharyya, Anandita De, Shiraz Minwalla +2
We study invariant solutions of the classical vacuum Einstein equations in dimensions. In the limit with held fixed we construct a class of sol…
Phase Structure of Higher Spin Black Holes
Abhishek Chowdhury, Arunabha Saha
We revisit the study of the phase structure of higher spin black holes carried out in arXiv using the "canonical formalism". In particular we study the low as well as h…
Black Hole Bound State Metamorphosis
Abhishek Chowdhury, Shailesh Lal, Arunabha Saha +1
N=4 supersymmetric string theories contain negative discriminant states whose numbers are known precisely from microscopic counting formulae. On the macroscopic side, these results…
One loop partition function for Topologically Massive Higher Spin Gravity
Arjun Bagchi, Shailesh Lal, Arunabha Saha +1
We calculate the one loop partition function for topologically massive higher spin gravity (TMHSG) for arbitrary spin by taking the spin-3 TMHSG action constructed in arXiv:1107.09…
Topologically Massive Higher Spin Gravity
Arjun Bagchi, Shailesh Lal, Arunabha Saha +1
We look at the generalisation of topologically massive gravity (TMG) to higher spins, specifically spin-3. We find a special "chiral" point for the spin-three, analogous to the spi…
Quantum W-symmetry in AdS_3
Matthias R. Gaberdiel, Rajesh Gopakumar, Arunabha Saha
It has recently been argued that, classically, massless higher spin theories in AdS_3 have an enlarged W_N-symmetry as the algebra of asymptotic isometries. In this note we provide…
