Abstract

The nonequilibrium properties of the anisotropic quark-gluon plasma are con- didered from the holographic viewpoint. Lifshitz-like solution is considered as a holo- graphic dual of anisotropic QGP. The black brane formation in such background is con- sidered as a thermalization in dual theory. As a probe of thermalization we consider rectangular spatial Wilson loops with different orientation.

Summary

Introduction and holographic setup

Gauge/gravity duality is a powerful tool for strong coupling systems equilibration study. Holographic description [6] of the HIC modeled by shock wall collisions in the Lifshitz-like background [10, 11], parametrized by the critical exponent ν is based on background d s2. This background perfectly matches experimental data [6] for holographic multiplicity calculation. We study (pseudo)potentials calculated from holographic Wilson loops and their evolution in asymptotically Lifshitz-like backgrounds. A non-zero temperature generalization of the Lifshitz-like spacetime (1) is a black brane background with the metric [8].
