Description
Summary:The existence of a magnetic birefringence of vacuum is one of the most important predictions of quantum electrodynamics, which has not yet been verified. In this contribution, we present a new project, the BMV (Birefringence Magnetique du Vide) project, a collaboration between different Grenoble, Lyon, and Toulouse institutes. The proposed experimental set-up, compared to previous attempts, should improve the signal level by about two orders of magnitude. Keystones of the proposed set-up are a very sensitive ellipsometer and a specially designed 1.5 m long, 25 T pulsed magnet, which is under development in Toulouse, France. (Author)
