Exploring the QED vacuum with laser interferometers
arXiv:hep-ph/0204207
Abstract
It is demonstrated that the nonlinear, and as yet unobserved, QED effect of slowing down light by application of a strong magnetic field may be observable with large laser interferometers like for instance LIGO or GEO600.
