Meson turbulence at quark deconfinement from AdS/CFT

Abstract
Based on the QCD string picture at confining phase, we conjecture that the deconfinement transition always accompanies a condensation of higher meson resonances with a power-law behavior, "meson turbulence". We employ the AdS/CFT correspondence to calculate the meson turbulence for supersymmetric QCD at large and at strong coupling limit, and find that the energy distribution to each meson level scales as with the universal scaling . The universality is checked for various ways to attain the quark deconfinement: a static electric field below/around the critical value, a time-dependent electric field quench, and a time-dependent quark mass quench, all result in the turbulent meson condensation with the universal power around the deconfinement.
