Summary

In this paper, we're going to explore the $ U_A(1) $ symmetry broken and anomaly current in a parallel electromagnetic field.We relax the SU(2) Nambu-Jona-Lasinio (NJL) model to investigate the condensations induced by electromagnetic field which contains chiral condensation, $ \pi^0,\eta $ condensation and mass splitting. We also calculate the $ U_A(1) $ susceptibility, which reflects the degree of the $ U_A(1) $ symmetry broken.
