Torsion-induced chiral magnetic current in equilibrium

We study equilibrium transport properties of massless Dirac fermions at finite temperature and chemical potential in spacetime accompanied by torsion, which four dimensions couples with as an axial gauge field. In particular, we compute the current density linear order torsion well external magnetic field Pauli–Villars regularization, finding that akin to chiral is locally induced. Such can be realized condensed matter systems along a screw dislocation line, around localized extended distributions are predicted so relevant Weyl semimetals. Furthermore, node separation, turns out vanish spite being allowed from symmetry perspective. Contrasts our findings torsion-induced currents previous work also discussed.
