Quantum vacuum magneto-optics

In this article we report on the recent experimental activities concerning the magneto-optics of quantum vacuum performed by our team based at the LNCMI of Toulouse. In particular, we will deal with quantum vacuum Cotton–Mouton and inverse Cotton–Mouton effects which have been predicted in the framework of Quantum electrodynamics. Finally, we will present our experiment on photon oscillations into massive particles in the presence of a magnetic field, an effect that could be a signature of physics beyond the standard model.
