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

Horava-Lifshitz Black Hole Hydrodynamics [PDF]
, 2014 We consider the holographic hydrodynamics of black holes in generally covariant gravity theories with a preferred time foliation. Gravitational perturbations in these theories have spin two and spin zero helicity modes with generically different speeds ...

Holographic constraints on Bjorken hydrodynamics at finite coupling
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.

Aspects of hot Galilean field theory [PDF]
, 2014 We reconsider general aspects of Galilean-invariant thermal field theory. Using the proposal of our companion paper, we recast non-relativistic hydrodynamics in a manifestly covariant way and couple it to a background spacetime.

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

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.

Hydrodynamic flow structures in quantum field theory [PDF]
AIP Conference Proceedings, 1984 The transport of matter is examined in the context of relativistic quantum transport theory for the case of neutral scalar fields. The goal is to formulate a theory valid off mass shell and out of equilibrium. We construct a conserved moment tensor which coincides with the ensemble average of the Noether tensor, or the improved energy‐momentum tensor ...

Hydrodynamic Self-Consistent Field Theory for Inhomogeneous Polymer Melts [PDF]
Physical Review Letters, 2006 We introduce a mesoscale technique for simulating the structure and rheology of block copolymer melts and blends in hydrodynamic flows. The technique couples dynamic self consistent field theory (DSCFT) with continuum hydrodynamics and flow penalization to simulate polymeric fluid flows in channels of arbitrary geometry.

Transport in the sine-Gordon field theory: from generalized hydrodynamics to semiclassics [PDF]
, 2019 The semiclassical approach introduced by Sachdev and collaborators proved to be extremely successful in the study of quantum quenches in massive field theories, both in homogeneous and inhomogeneous settings.
