Abstract
We examine the propagation of light in the presence of various modifications of the QED vacuum in the limit of low frequency. A polarization summed and direction averaged-light cone condition is derived from the equation of motion which arises from the effective QED action. Several applications are given concerning vacuum modifications caused by, e.g., strong fields, Casimir systems and finite temperature.
