Description

We present a first principles approach to study the dynamics of the Chiral Magnetic Effect and Chiral Magnetic Wave based on real-time lattice simulations with dynamical (Wilson and Overlap) fermions simultaneously coupled to color and electro-magnetic fields. We discuss how these techniques can be used to study the Chiral Magnetic Effect during the pre-equilibrium stage of a heavy-ion collision and present first results obtained within a simplified setup. While for light quarks we observe a dissipationless transport of charges as in anomalous hydrodynamics, we demonstrate that for heavier quarks the effects of explicit chiral symmetry breaking lead to a significant reduction of the associated currents. Within our microscopic approach, we also extract the spectral properties of the fermion fields to establish an intuitive picture of what flows in the Chiral Magnetic Effect.
