Generalized hydrodynamics of classical integrable field theory: the sinh-Gordon model

SciPost Physics, 2018
Using generalized hydrodynamics (GHD), we develop the Euler hydrodynamics of classical integrable field theory. Classical field GHD is based on a known formalism for Gibbs ensembles of classical fields, that resembles the thermodynamic Bethe ansatz of

Boost-invariant superfluid flows

Journal of High Energy Physics, 2022
We present some exact solutions to the ideal hydrodynamics of a relativistic superfluid with an almost-conformal equation of state. The solutions have stress tensors which are invariant under Lorentz boosts in one direction, and represent superfluid ...

Aspects of hydrodynamics in AdS/CMT [PDF]

, 2013
Condensed matter theory is the study of systems at finite density. In this thesis we will attempt to argue that gauge-gravity dualities can give deep and meaningful insights into the behaviour of strongly coupled condensed matter systems. The first three

Classical field theory

, 2019
Classical field theory predicts how physical fields interact with matter, and is a logical precursor to quantum field theory. This introduction focuses purely on modern classical field theory, helping graduates and researchers build an understanding of ...

New, Spherical Solutions of Non-Relativistic, Dissipative Hydrodynamics

Entropy, 2022
We present a new family of exact solutions of dissipative fireball hydrodynamics for arbitrary bulk and shear viscosities. The main property of these solutions is a spherically symmetric, Hubble flow field. The motivation of this paper is mostly academic:

Three-point functions from a Schwinger-Keldysh effective action, resummed in derivatives

Journal of High Energy Physics
The search for the conjectured QCD critical point in heavy-ion collisions requires to account for far-from equilibrium effects as well as fluctuations, and in particular non-Gaussian fluctuations, in the modeling of the dynamics of the hot and dense ...

Causal and stable superfluid hydrodynamics

Journal of High Energy Physics
We investigate the linearized stability and causality properties of relativistic viscous superfluid hydrodynamics. The Landau-Lifshitz-Clark-Putterman formulation for the theory of relativistic viscous superfluids suffers from the same instability and ...

Hydrodynamics as v s → c

Journal of High Energy Physics
I present the simplest 3+1 dimensional quantum field theory for which the speed of sound can be arbitrarily close to the speed of light. Examining the hydrodynamics, I find cases where the shear viscosity is finite, but the “shear relaxation coefficient”

Diffusion coefficient matrix for multiple conserved charges: a Kubo approach

Journal of High Energy Physics
The strongly interacting matter created in relativistic heavy-ion collisions possesses several conserved quantum numbers, such as baryon number, strangeness, and electric charge.
