Title: Properties of photons in supercritical magnetic fields

Abstract:I discuss effects of supercritical magnetic fields on photon propagations on the basis of a resummation technique by the proper-time method. I show the refractive index and decay rate of a real photon obtained from the vacuum polarization diagram, and also discuss the photon splitting from triangle diagrams in magnetic fields.
