Viscoelastic hydrodynamics and holography [PDF]

open access: yesJournal 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 ...

Holography and hydrodynamics with weakly broken symmetries [PDF]

open access: yesPhysical Review D, 2019
Hydrodynamics is a theory of long-range excitations controlled by equations of motion that encode the conservation of a set of currents (energy, momentum, charge, etc.) associated with explicitly realized global symmetries.

U(1) quasi-hydrodynamics: Schwinger-Keldysh effective field theory and holography

open access: yesJournal of High Energy Physics, 2023
We study the quasi-hydrodynamics of a system with a softly broken U(1) global symmetry using effective field theory (EFT) and holographic methods. In the gravity side, we consider a holographic Proca model in the limit of small bulk mass, which is ...

Pseudo-spontaneous U(1) symmetry breaking in hydrodynamics and holography [PDF]

open access: yesJournal of High Energy Physics, 2022
We investigate the low-energy dynamics of systems with pseudo-spontaneously broken U(1) symmetry and Goldstone phase relaxation. We construct a hydrodynamic framework which is able to capture these, in principle independent, effects.

Hydrodynamics with multiple charges and holography

open access: yesJournal of High Energy Physics
We establish the connection between thermodynamic and dynamical instabilities in relativistic hydrodynamics with multiple flavours of conserved U(1) charges.

Convergence of hydrodynamic modes: insights from kinetic theory and holography [PDF]

open access: yesSciPost Physics, 2021
We study the mechanisms setting the radius of convergence of hydrodynamic dispersion relations in kinetic theory in the relaxation time approximation. This introduces a quali\-tatively new feature with respect to holography: a nonhydrodynamic sector represented by a branch cut in the retarded Green's function.

Topological hydrodynamic modes and holography

open access: yesPhysical Review D, 2022
We study topological modes in relativistic hydrodynamics by weakly breaking the conservation of energy momentum tensor. Several systems have been found to have topologically nontrivial crossing nodes in the spectrum of hydrodynamic modes and some of them are only topologically nontrivial with the protection of reflection symmetries in two directions ...

Holography and hydrodynamics: diffusion on stretched horizons [PDF]

open access: yesJournal of High Energy Physics, 2003
We show that long-time, long-distance fluctuations of plane-symmetric horizons exhibit universal hydrodynamic behavior. By considering classical fluctuations around black-brane backgrounds, we find both diffusive and shear modes. The diffusion constant and the shear viscosity are given by simple formulas, in terms of metric components.

Resurgence and hydrodynamic attractors in Gauss-Bonnet holography [PDF]

open access: yesJournal of High Energy Physics, 2018
Abstract We study the convergence of the hydrodynamic series in the gravity dual of Gauss-Bonnet gravity in five dimensions with negative cosmological constant via holography. By imposing boost invariance symmetry, we find a solution to the Gauss-Bonnet equation of motion in inverse powers of the proper time, from which we can ...
