Effective actions for anomalous hydrodynamics
Felix M. Haehl, R. Loganayagam, Mukund Rangamani
We argue that an effective field theory of local fluid elements captures the constraints on hydrodynamic transport stemming from the presence of quantum anomalies in the underlying…
Holographic entanglement and causal information in coherent states
Simon A. Gentle, Mukund Rangamani
Scalar solitons in global AdS4 are holographically dual to coherent states carrying a non-trivial condensate of a scalar operator. We study the holographic information content of t…
The Spectrum of Light States in Large N Minimal Models
Matthias R. Gaberdiel, Rajesh Gopakumar, Mukund Rangamani
minimal models possess an interesting class of `light' primaries which control much of the low energy density of states in the large 't Hooft limit. In this paper we…
Global properties of causal wedges in asymptotically AdS spacetimes
Veronika E. Hubeny, Mukund Rangamani, Erik Tonni
We examine general features of causal wedges in asymptotically AdS spacetimes and show that in a wide variety of cases they have non-trivial topology. We also prove some general re…
Comments on Hall transport from effective actions
Felix M. Haehl, Mukund Rangamani
We consider parity-odd transport in 2+1 dimensional charged fluids restricting attention to the class of non-dissipative fluids. We show that there is a two parameter family of suc…
Effective hydrodynamics of black D3-branes
Roberto Emparan, Veronika E Hubeny, Mukund Rangamani
The long-wavelength effective field theory of world-volume fluctuations of black D3-branes is shown to be a hydrodynamical system to leading order in a gradient expansion. We study…
