Spatially Assisted Schwinger Mechanism, Chiral Magnetic Effect, and Magnetic Catalysis

抄録

Spatially inhomogeneous magnetic fields superimposed with parallel dynamically assisting electric fields, which are known to improve the Schwinger mechanism, are investigated using the worldline formalism. Due to a quadratic reduction in the fermion mass from the inhomogeneity of the magnetic field, it is found that the rate for Schwinger pair production, the chiral magnetic effect (attributed to pair production chirality generation), and the dynamical fermion mass, resulting from a vacuum reorganization, and hence magnetic catalysis are enhanced.
