Chiral magnetic effect in the Dirac–Heisenberg–Wigner formalism

In this paper the emergence of the Chiral Magnetic Effect (CME) and the related anomalous current is investigated using the real time Dirac–Heisenberg–Wigner formalism. This method is widely used for describing strong field physics and QED vacuum tunneling phenomena as well as pair production in hea...
