Recently, it turned out that the chiral anomaly gives rise to macroscopic transport phenomena. On such example is the chiral magnetic effect(CME), which is a phenomenon that an electric current is generated along an applied magnetic field. Those currents are non-dissipative, and are naturally incorporated into hydrodynamic equations, which are called anomalous hydrodynamics.
Theoretically, the CME should be happening in heavy-ion collisions.
The data reported by STAR and PHENIX collaborations at RHIC and ALICE collaborations at the LHC show a behavior consistent with the CME, but the quantitative understanding is still lacking. In order to reach a definitive conclusion, a reliable theoretical tool that can describe the charge-dependent observables is indispensable.
In this talk, we report our recent attempt of quantitative modeling of the CME for heavy-ion collisions. Basing on the event-by-event hydrodynamic simulations for hundreds of thousands of collisions, we calculate the correlation functions that are measured in experiments, and discuss how the anomalous transports affect the observables.
If time allows, I will also talk about the change of the topology of magnetic fields caused by the chiral anomaly.
