摘要:

As an important QED effect to detect the vacuum polarization, birefringence in the presence of a strong electric and magnetic field, E0B0,E0cB0, is considered. The directional dependence of birefringence is obtained. In two special cases: E0 = 0 and E0 = cB0, our results are consistent with the previous ones. The refractive index of the probe wave propagating in the E0×B0 direction decreases with E0/cB0, while that in the -E0×B0 direction increases with E0/cB0. The physics of the direction dependence of birefringence maybe the E0×B0 drift velocity of the virtual electrons and positrons.

关键词: vacuum birefringence, critical Schwinger field, refractive index, E×, B drift
