Description
We present a study of the out-of-equilibrium properties of the Chiral Magnetic Effect (CME) and the Chiral Separation Effect (CSE), both from the perturbation theory and lattice QCD perspectives. We discuss the analytic result of the retarded correlators and spectral functions of these effects at 1-loop in perturbation theory, generalizing the calculation to finite spatial momentum. The properties of these correlators shed light on the nature of the CME and CSE in a system of non-interacting fermions, but they also have substantial implications for interactive systems like QCD. We then determine the Euclidean correlators as a function of the (imaginary) time using full dynamical lattice QCD simulations at the physical point, analyzing some of its non-perturbative characteristics, which we show to coincide with results derived in 1-loop perturbation theory. Finally, we discuss the implications of our results for the out-of-equilibrium conductivities of these phenomena in QCD.
