, 2018 Since holography yields exact results, even in situations where perturbation theory is not applicable, it is an ideal framework for modeling strongly correlated systems.

Robinson-Trautman spacetimes and gauge/gravity duality
, 2017 We study far-from-equilibrium field theory dynamics using gauge/gravity duality applied to the Robinson-Trautman (RT) class of spacetimes and we present a number of new results.

Flat space compressible fluid as holographic dual of black hole with curved horizon
, 2015 We consider the fluid dual of $(d+2)$-dimensional vacuum Einstein equation either with or without a cosmological constant. The background solutions admit black hole event horizons and the spatial sections of the horizons are conformally flat.

Chiral magnetic waves in strongly coupled Weyl semimetals
Journal of High Energy PhysicsPropagating chiral magnetic waves (CMW) are expected to exist in chiral plasmas due to the interplay between the chiral magnetic and chiral separation effects induced by the presence of a chiral anomaly. Unfortunately, it was pointed out that, because of

Notes on resonances and unitarity from celestial amplitudes
Journal of High Energy Physics, 2022 We study the celestial description of the O(N) sigma model in the large N limit as introduced by Coleman, Jackiw and Politzer. Focusing on three dimensions, we analyze the implications of a UV complete, all-loop order 4-point amplitude of pions in terms ...

Transport Coefficients for Holographic Hydrodynamics at Finite Energy Scale [PDF]
, 2014 We investigate the relations between black hole thermodynamics and holographic transport coefficients in this paper. The formulae for DC conductivity and diffusion coefficient are verified for electrically single-charged black holes.

Dissipative electrically driven fluids
Journal of High Energy PhysicsWe consider entropy generating flows for fluids that achieve a steady state in the presence of a driving electric field. Having chosen one among the space of stationarity constraints that define such flows we show how energy and momentum relaxation are ...

Three-point functions from a Schwinger-Keldysh effective action, resummed in derivatives
Journal of High Energy PhysicsThe search for the conjectured QCD critical point in heavy-ion collisions requires to account for far-from equilibrium effects as well as fluctuations, and in particular non-Gaussian fluctuations, in the modeling of the dynamics of the hot and dense ...

Time evolving fluid from Vaidya spacetime
, 2017 A time evolving fluid system is constructed on a timelike boundary hypersurface at finite cutoff in Vaidya spacetime. The approach used to construct the fluid equations is a direct extension of the ordinary Gravity/Fluid correspondence under the ...

Quasi-normal modes of dyonic black holes and magneto-hydrodynamics
Journal of High Energy Physics, 2022 We revisit the magneto-hydrodynamics in (2+1) dimensions and confirm that it is consistent with the quasi-normal modes of the (3+1) dimensional dyonic black holes in the most general set-up with finite density, magnetic field and wave vector.
