Microstate Dependence of Scattering from the D1-D5 System
Sumit R. Das, Gautam Mandal
We investigate the question of distinguishing between different microstates of the D1-D5 system (with charges Q_1 and Q_5), by scattering with an incoherent beam, composed of a sup…
On the Thermodynamic Geometry of Hot QCD
Stefano Bellucci, Vinod Chandra, Bhupendra Nath Tiwari
We study the nature of the covariant thermodynamic geometry arising from the free energy of hot QCD. We systematically analyze the underlying equilibrium thermodynamic configuratio…
Quiver Topology and RG Dynamics
Vijay Balasubramanian, Bartlomiej Czech, Alfred D. Shapere +1
Renormalization group flows of quiver gauge theories play a central role in determining the low-energy properties of string vacua. We demonstrate that useful predictions about the…
Hawking Radiation and Quantum Anomaly in AdS2/CFT1 Correspondence
Takeshi Morita
In order to understand a boundary description of Hawking radiation in the AdS/CFT correspondence, we investigate the trace anomaly method in AdS space. In this method, Hawking…
The Incompressible Non-Relativistic Navier-Stokes Equation from Gravity
Sayantani Bhattacharyya, Shiraz Minwalla, Spenta R. Wadia
We note that the equations of relativistic hydrodynamics reduce to the incompressible Navier-Stokes equations in a particular scaling limit. In this limit boundary metric fluctuati…
Constraints on "rare" dyon decays
Sunil Mukhi, Rahul Nigam
We obtain the complete set of constraints on the moduli of N=4 superstring compactifications that permit "rare" marginal decays of 1/4-BPS dyons to take place. The constraints are…
Higher-derivative 3-algebras
Mohsen Alishahiha, Sunil Mukhi
Starting with the N=8 supersymmetric Yang-Mills theory on D2-branes and incorporating higher-derivative corrections to lowest nontrivial order, we perform a duality to derive the L…
Conformal Nonlinear Fluid Dynamics from Gravity in Arbitrary Dimensions
Sayantani Bhattacharyya, R. Loganayagam, Ipsita Mandal +2
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 se…
Hydrodynamics from charged black branes
Nabamita Banerjee, Jyotirmoy Bhattacharya, Sayantani Bhattacharyya +3
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…
Gauge Theories with Time Dependent Couplings and their Cosmological Duals
Adel Awad, Sumit R. Das, Suresh Nampuri +2
We consider the N=4 SYM theory in flat 3+1 dimensional spacetime with a time dependent coupling constant which vanishes at , like . In an analogous quantum mecha…
D2 to D2
Bobby Ezhuthachan, Sunil Mukhi, Constantinos Papageorgakis
Starting from maximally supersymmetric (2+1)d Yang-Mills theory and using a duality transformation due to de Wit, Nicolai and Samtleben, we obtain the ghost-free Lorentzian 3-algeb…
A note on matrix model with IR cutoff and AdS/CFT
Tanay K. Dey, Sudipta Mukherji, Subir Mukhopadhyay +1
We propose an effective model of strongly coupled gauge theory at finite temperature on in the presence of an infrared cutoff. It is constructed by considering the theory on…
Superconformal Indices for Chern Simons Theories
Jyotirmoy Bhattacharya, Shiraz Minwalla
Aharony, Bergman, Jafferis and Maldacena have recently proposed a dual gravitational description for a family of superconformal Chern Simons theories in three spacetime dimensions.…
Thermodynamics of Plasmaballs and Plasmarings in 3+1 Dimensions
Shanthanu Bhardwaj, Jyotirmoy Bhattacharya
We study localized plasma configurations in 3+1 dimensional massive field theories obtained by Scherk-Schwarz compactification of 4+1 dimensional CFT to predict the thermodynamic p…
Forced Fluid Dynamics from Gravity
Sayantani Bhattacharyya, R. Loganayagam, Shiraz Minwalla +3
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…
Consistent holographic description of boost-invariant plasma
Michal P. Heller, R. Loganayagam, Michal Spalinski +2
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…
M2-branes on M-folds
Jacques Distler, Sunil Mukhi, Constantinos Papageorgakis +1
We argue that the moduli space for the Bagger-Lambert A_4 theory at level k is (R^8 \times R^8)/D_{2k}, where D_{2k} is the dihedral group of order 4k. We conjecture that the theor…
Local Fluid Dynamical Entropy from Gravity
Sayantani Bhattacharyya, Veronika E Hubeny, R. Loganayagam +5
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 de…
Tachyon condensation and quark mass in modified Sakai-Sugimoto model
Avinash Dhar, Partha Nag
This paper continues the investigation of the modified Sakai-Sugimoto model proposed in arXiv:0708.3233. Here we discuss in detail numerical solutions to the classical equations fo…
Comments on 1/16 BPS Quantum States and Classical Configurations
Lars Grant, Pietro A. Grassi, Seok Kim +1
We formulate the problem of counting 1/16 BPS states of N = 4 Yang Mills theory as the enumeration of the local cohomology of an operator acting on holomorphic fields on C^2. We st…
M2 to D2
Sunil Mukhi, Constantinos Papageorgakis
We examine the recently proposed "3-algebra" field theory for multiple M2-branes and show that when a scalar field valued in the 3-algebra develops a vacuum expectation value, the…
Counting all dyons in N =4 string theory
Atish Dabholkar, Joao Gomes, Sameer Murthy
For dyons in heterotic string theory compactified on a six-torus, with electric charge vector Q and magnetic charge vector P, the positive integer I = g.c.d.(Q \wedge P) is an inva…
Degeneracy of Decadent Dyons
Atish Dabholkar, K. Narayan, Suresh Nampuri
A quarter-BPS dyon in super Yang-Mills theory is generically `decadent' in that it is stable only in some regions of the moduli space and decays on submanifolds in…
Entropy Current in Conformal Hydrodynamics
R. Loganayagam
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…
