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 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 ...

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.

Quasinormal modes of charged magnetic black branes & chiral magnetic transport
Journal of High Energy Physics, 2017 We compute quasinormal modes (QNMs) of the metric and gauge field perturbations about black branes electrically and magnetically charged in the Einstein-Maxwell-Chern-Simons theory. By the gauge/gravity correspondence, this theory is dual to a particular

Hydrodynamics, spin currents and torsion
Journal of High Energy Physics, 2023 We construct the canonical constitutive relations for a fluid description of a system with a spin current, valid in an arbitrary number of dimensions in the absence of parity breaking or time reversal breaking terms. Our study encompasses the hydrostatic

Feynman rules for forced wave turbulence
Journal of High Energy Physics, 2023 It has long been known that weakly nonlinear field theories can have a late-time stationary state that is not the thermal state, but a wave turbulent state with a far-from-equilibrium cascade of energy.

Determining all thermodynamic transport coefficients for an interacting large N quantum field theory
Journal of High Energy Physics, 2023 Thermodynamic transport coefficients can be calculated directly from quantum field theory without requiring analytic continuation to real time. We determine all second-order thermodynamic transport coefficients for the uncharged N-component massless ...

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.
