Classical versus non-classical photon states for detecting vacuum non-linearity
N. Ahmadiniaz, C. Kohlfürst, R. Shaisultanov +1
Quantum electrodynamics (QED) predicts that the vacuum should behave as a non-linear medium. For many schemes aimed at verifying this fundamental prediction, the signal consists of…

Letter of Intent: Towards a Vacuum Birefringence Experiment at the Helmholtz International Beamline for Extreme Fields
N. Ahmadiniaz, C. Bähtz, A. Benediktovitch +49
Quantum field theory predicts a nonlinear response of the vacuum to strong electromagnetic fields of macroscopic extent. This fundamental tenet has remained experimentally challeng…
