Abstract: Chiral Magnetic Effect (CME) is the macroscopic manifestation of the fundamental chiral anomaly in a many-body system of chiral fermions, and emerges as a generic anomalous transport current in the hydrodynamic framework. The study of CME has attracted significant recent interest across many disciplines from condensed matter to nuclear physics. An experimental observation of CME in heavy ion collisions would further provide the tantalizing evidence for the chiral symmetry restoration as well as QCD topological fluctuations. Currently the most pressing theoretical challenge is the quantitative modeling of CME while also accounting for background contamination. We report a significant step forward toward this goal, by the development of the Event-By-Event Anomalous Viscous Fluid Dynamics (EBE-AVFD) framework. This allows the state-of-the-art quantitative predictions for the CME signals in isobaric collisions (RuRu v.s. ZrZr) at RHIC, which will provide the most critical test of the CME in heavy ion collisions.
