Effective field theory for hydrodynamics: Thermodynamics, and the derivative expansion

open access: yesPhysical Review D, 2012
We consider the low-energy effective field theory describing the infrared dynamics of non-dissipative fluids. We extend previous work to accommodate conserved charges, and we clarify the matching between field theory variables and thermodynamical ones. We discuss the systematics of the derivative expansion, for which field theory offers a conceptually ...

DBI scalar field theory for QGP hydrodynamics [PDF]

open access: yesPhysical Review D, 2016
A way to describe the hydrodynamics of the quark-gluon plasma using a 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 ...

Stochastic methods in quantum field theory and hydrodynamics

Physics Reports, 1981
Abstract We give a review of recent work in quantum field theory and hydrodynamics, in which methods of stochastic analysis, in particular of stochastic equations, are used. The review includes the discussion of the canonical formalism for models of quantum fields as well as the discussion of statistical solutions of the Euler equations for the ...

Hydrodynamic theory of electromagnetic fields in continuous media

Physical Review Letters, 1993
The hydrodynamic Maxwell equations of continuous media, valid for large amplitudes and small frequencies, are derived. As any hydrodynamic theory, these equations are universal, nonlinear, and irreversible. Consequences for dielectric liquids, ferrofluids, superconductors, and nematic liquid crystals are briefly outlined.
