chiral magnetic effect (cme) is the generation of electric current along an external magnetic field induced by chirality imbalance. the cme is a macroscopic quantum phenomenon present in systems with charged chiral fermions, such as the quark-gluon plasma, or dirac and weyl semimetals; for review, see. the cme is a consequence of chiral anomaly in quantum field theory; unlike conventional superconductivity or superfluidity, it does not require a spontaneous symmetry breaking. the chiral magnetic current is non-dissipative, because it is topologically protected: the imbalance between the densities of left- and right-handed chiral fermions is linked to the topology of fields in gauge theory by the atiyah-singer index theorem.
