Summary
In this talk, we’re going to show the quantum dynamics for constant pseudo electromagnetic field which couples to the chirality charges of fermions in the framework of Schwinger’s proper-time integration. Then, as a check of this quantum dynamics, the various anomalous phenomena under different circumstances with ordinary electromagnetic field are generalized to include pseudo electromagnetic field. Finally, as a further application of the quantum dynamics, the effect of pseudomagnetic field to chiral symmetry breaking is explored with Ginzburg-Landau approach and the pseudomagnetic anti-catalysis effect is discovered compared to the magnetic catalysis effect.
