Causal and Stable Superfluid Hydrodynamics
Raphael E. Hoult, Ashish Shukla
We investigate the linearized stability and causality properties of relativistic viscous superfluid hydrodynamics. The Landau-Lifshitz-Clark-Putterman formulation for the theory of…
Holographic complexity: braneworld gravity versus the Lloyd bound
Sergio E. Aguilar-Gutierrez, Ben Craps, Juan Hernandez +3
We explore the complexity equals volume proposal for planar black holes in anti-de Sitter (AdS) spacetime in 2+1 dimensions, with an end of the world (ETW) brane behind the horizon…
Carrollian Origins of Bjorken Flow
Arjun Bagchi, Kedar S. Kolekar, Ashish Shukla
Bjorken flow is among the simplest models of fluids moving near the speed of light () while Carroll symmetry arises as a contraction of Poincaré group when . We show th…

Ji Hoon Lee, Dominik Neuenfeld, Ashish Shukla
We study information theoretic properties of planar black hole microstates in 2 + 1 dimensional asymptotically anti-de Sitter spacetime, modeled by black holes with an end-of-the-w…
Second order equilibrium transport in strongly coupled supersymmetric Yang-Mills plasma via holography
Sebastian Grieninger, Ashish Shukla
A relativistic fluid in 3+1 dimensions with a global symmetry admits nine independent static susceptibilities at the second order in the hydrodynamic derivative expansion, w…

Parity preserving relativistic fluids in four spacetime dimensions admit seven independent thermodynamic susceptibilities at the second order in the hydrodynamic derivative expansi…
Kubo formulas for thermodynamic transport coefficients
Pavel Kovtun, Ashish Shukla
Uncharged relativistic fluids in 3+1 dimensions have three independent thermodynamic transport coefficients at second order in the derivative expansion. Fluids with a single global…

Adam Ritz, Ashish Shukla
We analyze the moduli space dynamics of domain walls in QCD at , by softly breaking SQCD with sfermion mixing. In the supersymmetric limit, BPS d…
