Title: Anomalous transport from non-equilibrium real time lattice simulations
Abstract: In recent years, a variety of chiral anomaly induced effects have been proposed in various physical systems, starting with high energy heavy ion collisions, and later in condensed matter and astrophysical settings. While some of these effects have been confirmed in condensed matter settings, in heavy ion collisions the experimental results from RHIC at BNL and the LHC at CERN show intriguing hints of the expected signal, however there are many theoretical uncertainties and the origin of these signals is ambiguous. In this talk, I will discuss recent progress in understanding anomaly induced transport at early times after a high energy heavy ion collision, namely the Chiral Magnetic Effect and Chiral Magnetic Wave, from first principles motivated real time lattice simulations. After giving an overview for the relevant physics and framework, I will discuss a first calculation of the rate of topological transitions, i.e. sphalerons, in an out of equilibrium non-Abelian plasma, similar to what is created at early times after a high energy heavy ion collision. I will then discuss a first time application of real time chiral fermions in a lattice description, and show how a sphaleron background with an external magnetic field can generate both the CME and CMW. I will then discuss the magnetic field and quark mass dependence on these results.
