Description
When chiral charged matter is exposed to extremely strong magnetic fields, novel hydrodynamic transport effects emerge 1. These novel effects need to be estimated and possibly taken into account, for example in the hydrodynamic codes used to analyze heavy-ion collision data or magnetars. Kubo formulae link the macroscopic transport coefficients to the microscopic retarded two-point correlation functions of conserved currents. Some among the transport effects cause no dissipation, i.e. they produce no entropy; one well known example is the chiral magnetic effect (CME). As a case study far away from equilibrium, the CME within holographic plasma suggests lessons for the quark-gluon-plasma at colliders 2.
