报告简介:
The dynamics of axial charge has been a key component of the celebrated chiral magneic effect (CME) and chiral magnetic wave (CMW) in heavy ion collisions. Due to the non-conservation of axial charge, the inclusion of axial charge in hydrodynamic equations is a subtle issue. On one hand, axial charge is generated by fluctuation owing to its non-conservation, on the other hand, the non-conservation also provide mechanism of charge dissipation. A more appropriate treatment is to use stochastic hydrodynamics for axial charge. In this talk, I will discuss two sources of non-conservation: topological transition and quark mass. Both of them will contribute to the fluctuation and dissipation of axial charge.
