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.

Hydrodynamic quantum field theory: the free particle [PDF]
Comptes 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 ...

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.

New dynamical realizations of the Lifshitz group
Nuclear Physics B, 2023 The method of nonlinear realizations is applied to construct new dynamical realizations of the Lifshitz group in mechanics, hydrodynamics, and field theory.

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. The theory, which is dictated by the requirement of Galilei invariance, entails the entire set of hydrodynamic equations.

Hydrodynamic transport coefficients in relativistic scalar field theory [PDF]
Physical 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

Relativistic fluid dynamics and its extensions as an effective field theory
, 2020 We examine hydrodynamics from the perspective of an effective field theory. The microscopic scale in this case is the thermalization scale, and the macroscopic scale is the gradient, with thermal fluctuations playing the role of (sic). We argue that this
