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

Hydrodynamic effective field theories with discrete rotational symmetry

Journal 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.

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 ...

Schwinger-Keldysh effective field theory for stable and causal relativistic hydrodynamics

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

Journal 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

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

Thermalization and hydrodynamics of two-dimensional quantum field theories

SciPost 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]

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.

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 ...
