Vacuum Birefringence, Ellipticity, and the Anomalous Magnetic Moment of a Photon

Sree Ram Valluri, Farrukh Chishtie, Wieslaw J. Mielniczuk

We study photon propagation in a strong magnetic field $B\sim B_{\mathrm{cr}}$, where $B_{\mathrm{cr}}=\frac{m^2}{e}\simeq 4.4\times 10^{13}$ Gauss is the Schwinger critical field. We sh…
