Effective Field Theory of ideal-fluid Hydrodynamics [PDF]

open access: yesModern 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.

Towards classical geometrodynamics from Group Field Theory hydrodynamics

open access: yesNew 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.

Hydrodynamic effective field theories with discrete rotational symmetry

open access: yesJournal of High Energy Physics, 2022
We develop a hydrodynamic effective field theory on the Schwinger-Keldysh contour for fluids with charge, energy, and momentum conservation, but only discrete rotational symmetry.

Viscosity and dissipative hydrodynamics from effective field theory [PDF]

open access: yesPhysical 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 ...

Hydrodynamics, anomaly inflow and bosonic effective field theory

open access: yesJournal 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.

Hydrodynamic and non-hydrodynamic excitations in kinetic theory — a numerical analysis in scalar field theory

open access: yesJournal of High Energy Physics, 2023
Abstract Viscous hydrodynamics serves as a successful mesoscopic description of the Quark-Gluon Plasma produced in relativistic heavy-ion collisions. In order to investigate, how such an effective description emerges from the underlying microscopic dynamics we calculate the hydrodynamic and non-hydrodynamic modes of linear response

Thermalization and hydrodynamics of two-dimensional quantum field theories

open access: yesSciPost Physics, 2022
We consider 2d QFTs as relevant deformations of CFTs in the thermodynamic limit. Using causality and KPZ universality, we place a lower bound on the timescale characterizing the onset of hydrodynamics. The bound is determined parametrically in terms of the temperature and the scale associated with the relevant deformation.

Hydrodynamic quantum field theory: the free particle [PDF]

open access: yesComptes Rendus. Mécanique, 2020
We revisit de Broglie’s double-solution pilot-wave theory in light of insights gained from the hydrodynamic pilot-wave system discovered by Couder and Fort [1]. de Broglie proposed that quantum particles are characterized by an internal oscillation at the Compton frequency, at which rest mass energy is exchanged with field energy.

Hydrodynamic transport coefficients in relativistic scalar field theory [PDF]

open access: yesPhysical Review D, 1995
Hydrodynamic transport coefficients may be evaluated from first principles in a weakly coupled scalar field theory at arbitrary temperature. In a theory with cubic and quartic interactions, the infinite class of diagrams which contribute to the leading weak coupling behavior are identified and summed. The resulting expression may be reduced to a single

Holographic thermal correlators: a tale of Fuchsian ODEs and integration contours

open access: yesJournal of High Energy Physics, 2023
We analyze real-time thermal correlation functions of conserved currents in holographic field theories using the grSK geometry, which provides a contour prescription for their evaluation.
