Effective field theory for non-relativistic hydrodynamics [PDF]

Journal of High Energy Physics, 2020
We write down a Schwinger-Keldysh effective field theory for non-relativistic (Galilean) hydrodynamics. We use the null background construction to covariantly couple Galilean field theories to a set of background sources.

Effective field theory for hydrodynamics without boosts [PDF]

SciPost Physics, 2021
We formulate the Schwinger-Keldysh effective field theory of hydrodynamics without boost symmetry. This includes a spacetime covariant formulation of classical hydrodynamics without boosts with an additional conserved particle/charge current coupled to ...

Hydrodynamics, anomaly inflow and bosonic effective field theory

Journal of High Energy Physics
Euler hydrodynamics of perfect fluids can be viewed as an effective bosonic field theory. In cases when the underlying microscopic system involves Dirac fermions, the quantum anomalies should be properly described.

Field Theory Approaches to Relativistic Hydrodynamics

Entropy, 2022
Just as non-relativistic fluids, oftentimes we find relativistic fluids in situations where random fluctuations cannot be ignored, with thermal and turbulent fluctuations being the most relevant examples.

Effective Field Theory of ideal-fluid Hydrodynamics [PDF]

Modern Physics Letters B, 1996
Starting from a standard description of an ideal, isentropic fluid, we derive the effective theory governing a gapless non-relativistic mode---the sound mode.

Viscosity and dissipative hydrodynamics from effective field theory [PDF]

Physical Review D, 2015
With the goal of deriving dissipative hydrodynamics from an action, we study classical actions for open systems, which follow from the generic structure of effective actions in the Schwinger-Keldysh Closed-Time-Path formalism with two time axes and a ...

Towards classical geometrodynamics from Group Field Theory hydrodynamics

New Journal of Physics, 2011
We take the first steps towards identifying the hydrodynamics of group field theories (GFTs) and relating this hydrodynamic regime to classical geometrodynamics of continuum space.

U(1) quasi-hydrodynamics: Schwinger-Keldysh effective field theory and holography

Journal of High Energy Physics, 2023
We study the quasi-hydrodynamics of a system with a softly broken U(1) global symmetry using effective field theory (EFT) and holographic methods. In the gravity side, we consider a holographic Proca model in the limit of small bulk mass, which is ...

Goldstone bosons and fluctuating hydrodynamics with dipole and momentum conservation

Journal of High Energy Physics, 2023
We develop a Schwinger-Keldysh effective field theory describing the hydrodynamics of a fluid with conserved charge and dipole moments, together with conserved momentum.

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
