Probing vacuum birefringence in an ultrastrong laser field via high-energy gamma-ray polarimetry
Vacuum birefringence (VB), a fundamental prediction of nonlinear QED, has eluded direct laboratory detection due to its extreme weakness. We propose a compact, “self-probing” scheme where a GeV electron beam collides head-on with a petawatt laser pulse. Circularly polarized γ-ray photons, generated...
