One loop photon-graviton mixing in an electromagnetic field: Part 3
Naser Ahmadiniaz, Fiorenzo Bastianelli, Felix Karbstein und Christian Schubert
Photon-graviton conversion in an electromagnetic field is a well-known prediction of Einstein-Maxwell theory. First discussed at tree-level by Gertsenshtein in 1962, more recently…

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…
