Holographic Rényi n → 0 entropy and Euclidean fluids

Journal of High Energy Physics
We explore the holographic prescription for computing the refined Rényi entropies S ~ n $$ {\overset{\sim }{S}}_n $$ in the n → 0 limit within the AdS d+1/CFT d framework.

Air-water two phase flow simulation using smoothed particle hydrodynamics

, 2012
a new method is proposed for air-water two phase flowsimulation using Smoothed Particle Hydrodynamics method: thetwo different fluid phases are treated separately within the same time step.

Field redefinitions and evolutions in relativistic Navier-Stokes

Journal of High Energy Physics
In recent years the equations of relativistic first-order viscous hydrodynamics, that is, the relativistic version of Navier-Stokes, have been shown to be well posed and causal under appropriate field redefinitions, also known as hydrodynamic frames.

Relativistic dispersion spectra across Lorentz boosted frames: spurious modes and causality

Journal of High Energy Physics
The analysis of excitation spectra in gradient-expanded relativistic fluid theories frequently leads to pathologies under Lorentz boosts. However, extracting the dispersion modes in a Lorentz boosted inertial frame can be nontrivial.

Hydrodynamization in hybrid Bjorken flow attractors

Journal of High Energy Physics
Hybrid fluid models, consisting of two sectors with more weakly and more strongly self-interacting degrees of freedom coupled consistently as in the semi-holographic framework, have been shown to exhibit an attractor surface for Bjorken flow.

Kubo formulas for spin polarization in dissipative relativistic spin hydrodynamics: a first-order gradient expansion approach

Journal of High Energy Physics
We use linear response theory to derive both the non-dissipative and dissipative effects of spin polarization for massive and massless interacting spin 1/2 particles in a relativistic fluid. We list and classify all the possible contributions up to first

Hybrid thermalization in the large N limit

Journal of High Energy Physics
Semi-holography provides a formulation of dynamics in gauge theories involving both weakly self-interacting (perturbative) and strongly self-interacting (non-perturbative) degrees of freedom.

A complex scalar field theory for charged fluids, superfluids, and fracton fluids

Journal of High Energy Physics
We propose a field-theoretic framework for ideal hydrodynamics of charged relativistic fluids formulated in terms of a complex scalar field defined on a spacelike hypersurface comoving with the fluid.

Large charge operators at large spin from relativistically rotating vortices

Journal of High Energy Physics
We study the ground states of CFTs with a global U(1) symmetry on ℝ × S 2 in the regime of large charge Q and large angular momentum J, using large charge EFT.

Generalised hydrodynamics of T T ¯ $$ \textrm{T}\overline{\textrm{T}} $$ -deformed integrable quantum field theories

Journal of High Energy Physics
In this paper we evaluate the averages of conserved densities and currents associated to charges of generic spin in (1+1)-dimensional massive integrable Quantum Field Theories perturbed by the irrelevant T T ¯ $$ \textrm{T}\overline{\textrm{T ...
