A way to describe the hydrodynamics of the quark-gluon plasma using a Dirac-Born-Infeld (DBI) action is proposed, based on the model found by Heisenberg for high energy scattering of nucleons. The expanding plasma is described as a shockwave in a DBI model for a real scalar standing in for the pion, and I show that one obtains a fluid description in terms of a relativistic fluid that near the shock is approximately ideal ($\ensuremath{\eta}\ensuremath{\simeq}0$) and conformal. One can introduce… 

Particle-vortex duality and theta terms in AdS/CMT applications

In this paper we study particle-vortex duality and the effect of theta terms from the point of view of AdS/CMT constructions. We can construct the duality in 2+1 dimensional field theories with or

Knotted solutions, from electromagnetism to fluid dynamics

Knotted solutions to electromagnetism and fluid dynamics are investigated, based on relations we find between the two subjects. We can write fluid dynamics in electromagnetism language, but only on

Black Hole Membrane Paradigm from Boundary Scalar Field

This paper shows that an action can be constructed from the scalar on the horizon which can give the same energy-momentum tensor for the membrane, which is to say, the membrane can be described effectively by the scalars on it.

Lagrangian Formulation, Generalizations and Quantization of Null Maxwell's Knots

Knotted solutions to electromagnetism are investigated as an independent subsector of the theory. We write down a Lagrangian and a Hamiltonian formulation of Bateman's construction for the knotted



DBI skyrmion, high energy (large s) scattering and fireball production

We analyze the high energy scattering of hadrons in QCD in an effective theory model inspired from a gravity dual description. The nucleons are skyrmion-like solutions of a DBI action, and boosted

More on Heisenberg’s model for high energy nucleon-nucleon scattering

We revisit Heisenberg's model for nucleon-nucleon scattering which admits a saturation of the Froissart bound. We examine its uniqueness, and find that up to certain natural generalizations, it is

Heisenberg saturation of the Froissart bound from AdS-CFT

Shear viscosity of strongly coupled N = 4 supersymmetric Yang-Mills plasma.

Using the anti-de Sitter/conformal field theory correspondence, the shear viscosity eta of the finite-temperature N = 4 supersymmetric Yang-Mills theory is related with the absorption cross section of low-energy gravitons by a near-extremal black three-brane and it is shown that in the limit of zero frequency this cross section coincides with the area of the horizon.

High energy QCD scattering, the shape of gravity on an IR brane, and the Froissart bound

High-energy scattering in nonconformal gauge theories is investigated using the AdS/conformal field theory (CFT) dual string-gravity theory. It is argued that strong-gravity processes, such as black

The RHIC fireball as a dual black hole

We argue that the fireball observed at RHIC is (the analog of) a dual black hole. In previous works, we have argued that the large $s$ behaviour of the total QCD cross section is due to production of

The Large-N Limit of Superconformal Field Theories and Supergravity

We show that the large-N limits of certainconformal field theories in various dimensions includein their Hilbert space a sector describing supergravityon the product of anti-de Sitter spacetimes,

Hadron production in Au – Au collisions at RHIC

We present an analysis of particle production yields measured in central Au–Au collisions at RHIC in the framework of the statistical thermal model. We demonstrate that the model extrapolated from

Viscosity information from relativistic nuclear collisions: how perfect is the fluid observed at RHIC?

Relativistic viscous hydrodynamic fits to Brookhaven Rel ativistic Heavy Ion Collider data on the centrality dependence of multiplicity, transverse, and elliptic flow for square root s = 200 GeV Au+Au collisions seem to favor a much smaller viscosity over entropy ratio, below the bound from the anti-de Sitter conformal field theory conjecture.

Particle production in heavy ion collisions

The status of thermal model descriptions of particle production in heavy ion collisions is presented. We discuss the formulation of statistical models with different implementation of the
