AdS/CFT and Landau Fermi liquids [PDF]
, 2014 We study the field theory dual to a charged gravitational background in which the low temperature entropy scales linearly with the temperature. We exhibit the existence of a sound mode which is described by hydrodynamics, even at energies much larger ...

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.

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.

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 ...

DBI scalar field theory for QGP hydrodynamics [PDF]
Physical Review D, 2016 A way to describe the hydrodynamics of the quark-gluon plasma using a DBI action is proposed, based on the model found by Heisenberg for high energy scattering of nucleons. The expanding plasma is described as a shockwave in a DBI model for a real scalar standing in for the pion, and I show that one obtains a fluid description in terms of a ...

Viscoelastic hydrodynamics and holography
Journal of High Energy Physics, 2020 We formulate the theory of nonlinear viscoelastic hydrodynamics of anisotropic crystals in terms of dynamical Goldstone scalars of spontaneously broken translational symmetries, under the assumption of homogeneous lattices and absence of plastic ...

Thermalization and chaos in a 1+1d QFT
Journal of High Energy Physics, 2023 We study aspects of chaos and thermodynamics at strong coupling in a scalar model using LCT numerical methods. We find that our eigenstate spectrum satisfies Wigner-Dyson statistics and that the coefficients describing eigenstates in our basis satisfy ...

Relativistic fluid dynamics and its extensions as an effective field theory
, 2019 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 $\hbar$.
