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 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.

Spectral form factor of a quantum spin glass
Journal of High Energy Physics, 2022 It is widely expected that systems which fully thermalize are chaotic in the sense of exhibiting random-matrix statistics of their energy level spacings, whereas integrable systems exhibit Poissonian statistics.

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 ...

Bridging Effective Field Theories and Generalized Hydrodynamics
, 2022 Generalized Hydrodynamics (GHD) has recently been devised as a method to solve the dynamics of integrable quantum many-body systems beyond the mean-field approximation. In its original form, a major limitation is the inability to predict equal-time correlations.

From quantum field theory to hydrodynamics: Transport coefficients and effective kinetic theory [PDF]
Physical Review D, 1996 The evaluation of hydrodynamic transport coefficients in relativistic field theory, and the emergence of an effective kinetic theory description, is examined. Even in a weakly-coupled scalar field theory, interesting subtleties arise at high temperatures where thermal renormalization effects are important.

Aspects of univalence in holographic axion models
Journal of High Energy Physics, 2022 Univalent functions are complex, analytic (holomorphic) and injective functions that have been widely discussed in complex analysis. It was recently proposed that the stringent constraints that univalence imposes on the growth of functions combined with ...
