Out-of-Equilibrium Chiral Magnetic Effect at Strong Coupling

Understand

We study the charge transports originating from triangle anomaly in out-of-equilibrium conditions in the framework of AdS/CFT correspondence at strong coupling, to gain useful insights on possible charge separation effects that may happen in the very early stages of heavy-ion collisions.

• We first construct a gravity background of a homogeneous mass shell with a finite (axial) charge density gravitationally collapsing to a charged blackhole, which serves as a dual model for out-of-equilibrium charged plasma undergoing thermalization.
• We find that a finite charge density in the plasma slows down the thermalization.
• We then study the out-of-equilibrium properties of Chiral Magnetic Effect and Chiral Magnetic Wave in this background.
