Small Hairy Black Holes in Global AdS Spacetime (2010)
Basu, Pallab, Bhattacharya, Jyotirmoy, Bhattacharyya, Sayantani, Loganayagam, R., Minwalla, Shiraz, Umesh, V.
We study small charged black holes in global AdS spacetime in the presence of a charged massless minimally coupled scalar field. In a certain parameter range these black holes suffer from well known...
Conformal Nonlinear Fluid Dynamics from Gravity in Arbitrary Dimensions (2008)
Bhattacharyya, Sayantani, Loganayagam, R., Mandal, Ipsita, Minwalla, Shiraz, Sharma, Ankit
We generalize recent work to construct a map from the conformal Navier Stokes equations with holographically determined transport coefficients, in d spacetime dimensions, to the set of asymptotically...
Hydrodynamics from charged black branes (2008)
Banerjee, Nabamita, Bhattacharya, Jyotirmoy, Bhattacharyya, Sayantani, Dutta, Suvankar, Loganayagam, R., Surówka, P.
We extend the recent work on fluid-gravity correspondence to charged black-branes by determining the metric duals to arbitrary charged fluid configuration up to second order in the boundary...
Forced Fluid Dynamics from Gravity (2008)
Bhattacharyya, Sayantani, Loganayagam, R., Minwalla, Shiraz, Nampuri, Suresh, Trivedi, Sandip P., Wadia, Spenta R.
We generalise the computations of arXiv:0712.2456 to generate long wavelength, asymptotically locally AdS_5 solutions to the Einstein-dilaton system with a slowly varying boundary dilaton field and a...
Consistent holographic description of boost-invariant plasma (2008)
Heller, Michal P., Loganayagam, R., Spalinski, Michal, Surowka, Piotr, Vazquez, Samuel E.
Prior attempts to construct the gravity dual of boost-invariant flow of N=4 supersymmetric Yang-Mills gauge theory plasma suffered from apparent curvature singularities in the late time expansion....
Local Fluid Dynamical Entropy from Gravity (2008)
Bhattacharyya, Sayantani, Hubeny, Veronika E, Loganayagam, R., Mandal, Gautam, Minwalla, Shiraz, Morita, Takeshi, ...
Spacetime geometries dual to arbitrary fluid flows in strongly coupled N=4 super Yang Mills theory have recently been constructed perturbatively in the long wavelength limit. We demonstrate that...
Entropy Current in Conformal Hydrodynamics (2008)
In recent work (arXiv:0712.2456, arXiv:0712.2451) the energy-momentum tensor for the N=4 SYM fluid was computed up to second derivative terms using holographic methods. The aim of this note is to...
Large rotating AdS black holes from fluid mechanics (2007)
Bhattacharyya, Sayantani, Lahiri, Subhaneil, Loganayagam, R., Minwalla, Shiraz
We use the AdS/CFT correspondence to argue that large rotating black holes in global AdS(D) spaces are dual to stationary solutions of the relativistic Navier-Stokes equations on S**(D-2). Reading...
We study the effect of long-range connections on the infinite-randomness fixed point associated with the quantum phase transitions in a transverse Ising model (TIM). The TIM resides on a long-range...
