Description

The time evolution of the energy transport triggered in a strongly coupled quantum critical system by a temperature gradient is holographically related to the evolution of an asymptotically AdS black brane with a gradient in its planar horizon. Of relevance in these systems is the appearance of a universal steady state, described by a boosted thermal state. A relevant observable that provides physical insight about the evolution of the system and the eventual formation of a steady state is the entanglement entropy. In this talk, I will study the far from equilibrium energy transport of such a system by using gauge/gravity duality, and present results for the time evolution of the entanglement entropy.
