Shock waves are supersonic disturbances propagating in a fluid and giving rise to dissipation and drag. Weak shocks, i.e., those of small amplitude, can be well described within the hydrodynamic approximation. On the other hand, strong shocks are discontinuous within hydrodynamics and therefore probe the microscopics of the theory. In this paper, we consider the case of the strongly coupled N=4 plasma whose microscopic description, applicable for scales smaller than the inverse temperature, is…

Shock waves in strongly coupled plasmas II

In a recent paper we have analyzed the AdS/CFT duals to shock waves propagating in the $ \mathcal{N} = 4 $ plasma. Here we study further properties of the system. In the gravity description we

Shocks in quark-gluon plasmas

Hydrodynamics is known to describe matter created in high energy heavy ion collisions well. Large deposition of energy by passing jets should create not only the sound waves, already discussed in

Steady asymptotic equilibria in conformal relativistic fluids

When one considers a shock wave in the frame where the shock is at rest, on either side one has a steady flow which converges to equilibrium away from the shock. However, hydrodynamics is unable to

Vorticesin(2+1)d conformal fluids

We study isolated, stationary, axially symmetric vortex solutions in (2+ 1)-dimensional viscous conformal fluids. The equations describing them can be brought to the form of three coupled first order

Stationary holographic plasma quenches and numerical methods for non-killing horizons.

This work explores use of the harmonic Einstein equations to numerically find stationary black holes where the problem is posed on an ingoing slice that extends into the interior of the black hole, and finds the first nonperturbative examples of stationary black hole which do not have Killing horizons.

Heavy ion collisions with transverse dynamics from evolving AdS geometries

Currently there exists no known way to construct the Stress-Energy Tensor (Tμν) of the produced medium in heavy ion collisions at strong coupling from purely theoretical grounds. In this paper, some

Surface Layers in the Gravity/Hydrodynamics Correspondence

I review the AdS/hydrodynamics correspondence, which provides a 1-1 map between large wavelength features of AdS black branes and conformal fluid flows. In this thesis I consider boundaries between

Overcoming obstacles in nonequilibrium holography

We study universal spatial features of certain nonequilibrium steady states corresponding to flows of strongly correlated fluids over obstacles. This allows us to predict universal spatial features

Holographic phase diagram of quark-gluon plasma formed in heavy-ion collisions

A bstractWe use a holographic dual model for the heavy-ion collision to obtain the phase diagram of the quark-gluon plasma (QGP) formed at a very early stage just after the collision. In this dual



Shockwaves and deep inelastic scattering within the gauge/gravity duality

Within the gauge/gravity correspondence, we discuss the general formulation of the shockwave metric which is dual to a `nucleus' described by the strongly-coupled = 4 SYM theory in the limit where

Shock treatment: Heavy quark drag in a novel AdS geometry

Modeling heavy ion collisions in AdS/CFT

We construct a model of high energy heavy ion collisions as two ultrarelativistic shock waves colliding in AdS5. We point out that shock waves corresponding to physical energy-momentum tensors of the

On gravitational shock waves in curved spacetimes

Relativistic shock waves in viscous gluon matter.

The relativistic Riemann problem in viscous gluon matter is solved employing a microscopic parton cascade and an eta/s ratio larger than 0.2 prevents the development of well-defined shock waves on time scales typical for ultrarelativistic heavy-ion collisions.

The gravitational shock wave of a massless particle

Exact Gravitational Shockwaves and Planckian Scattering on Branes

We obtain a solution describing a gravitational shockwave propagating along a Randall-Sundrum brane. The interest of such a solution is twofold: on the one hand, it is the rst exact solution for a

Nearly perfect fluidity: from cold atomic gases to hot quark gluon plasmas

Shear viscosity is a measure of the amount of dissipation in a simple fluid. In kinetic theory shear viscosity is related to the rate of momentum transport by quasi-particles, and the uncertainty

Local Fluid Dynamical Entropy from Gravity

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 production in collisions of gravitational shock waves and of heavy ions

We calculate the area of a marginally trapped surface formed by a head-on collision of gravitational shock waves in AdS{sub D}. We use this to obtain a lower bound on the entropy produced after the
