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 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 PhysicsEuler 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.

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.

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 ...

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

Holographic constraints on Bjorken hydrodynamics at finite coupling [PDF]
Journal of High Energy Physics, 2017 In large-N c conformal field theories with classical holographic duals, inverse coupling constant corrections are obtained by considering higher-derivative terms in the corresponding gravity theory.

Holographic viscoelastic hydrodynamics
Journal of High Energy Physics, 2019 Relativistic fluid hydrodynamics, organized as an effective field theory in the velocity gradients, has zero radius of convergence due to the presence of non-hydrodynamic excitations.

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