Anomalous currents in dense matter under a magnetic field
arXiv:1010.3923 · doi:10.1016/j.physletb.2011.04.010
Abstract
We consider fermionic dense matter under a magnetic field, where fermions couple minimally to gauge fields, and calculate anomalous currents at one loop. We find anomalous currents are spontaneously generated along the magnetic field but fermions only in the lowest Landau level contribute to anomalous currents. We then show that there are no more corrections to the anomalous currents from two or higher loops.
