Short-lived modes from hydrodynamic dispersion relations

open access: yes, 2018
We consider the dispersion relation of the shear-diffusion mode in relativistic hydrodynamics, which we generate to high order as a series in spatial momentum q for a holographic model.

Generalized planar black holes and the holography of hydrodynamic shear

open access: yesNuclear Physics B, 2014
AdS black holes with planar event horizon topology play a central role in AdS/CFT holography, and particularly in its applications. Generalisations of the known planar black holes can be found by considering the Plebanski--Demianski metrics, a very general family of exactly specified solutions of the Einstein equations.

Higgs/amplitude mode dynamics from holography

open access: yesJournal of High Energy Physics, 2022
Second order phase transitions are universally driven by an order parameter which becomes trivial at the critical point. At the same time, collective excitations which involve the amplitude of the order parameter develop a gap which smoothly closes to ...

Poor man's holography: How far can it go?

open access: yes, 2013
One of the most exciting things in recent theoretical physics is the suspicion that gravity may be holographic, dual to some sort of quantum field theory living on the boundary with one less dimension.

Towards Collisions of Inhomogeneous Shockwaves in AdS

open access: yes, 2015
We perform a numerical simulation of the evolution of inhomogeneities with transverse profile in a collision of gravitational shockwaves in asymptotically anti-de Sitter spacetime.

Viscosity of gauge theory plasma with a chemical potential from AdS/CFT correspondence [PDF]

open access: yes, 2006
We compute the strong coupling limit of the shear viscosity for the N=4 super-Yang-Mill theory with a chemical potential. We use the five-dimensional Reissner-Nordstrom-anti-deSitter black hole, so the chemical potential is the one for the R-charges U(1 ...

Holography, hydrodynamics and the transseries expansion

open access: yes, 2020
The transseries is an ansatz for generating solutions to classical problems which are both perturbative and non-perturbative in some limit of parameter space. In this thesis we apply this technique to three systems described by classical gravity with relevance to holographic plasmas of strongly coupled gauge theories. To begin we compute the gradient

Causality in dissipative relativistic magnetohydrodynamics

open access: yesJournal of High Energy Physics
We explore the relationship between linear and non-linear causality in theories of dissipative relativistic fluid dynamics. While for some fluid-dynamical theories, a linearized causality analysis can be used to determine whether the full non-linear ...

Holographic hydrodynamics of tilted Dirac materials

open access: yesJournal of High Energy Physics, 2023
We present a gravity dual to a quantum material with tilted Dirac cone in 2+1 dimensional spacetime. In this many-body system the electronics degrees of freedom are strongly-coupled, constitute a Dirac fluid and admit an effective hydrodynamic ...
