Description
Modern laser and detector technologies allow to propose and perform first photon-photon scattering experiments with real on-shell photons. However, for currently available technologies, the expected lightby-light signal is weak (only a few photons), especially compared to the huge laser background. Therefore, it is crucial to identify prospective scenarios for potential experimental measurement and provide quantitative estimates for them. Quantum reflection might be an interesting quantum vacuum signature due to the good separation of signal from background [1]. Using a linear Maxwell solver to describe the evolution of background fields [2] and the vacuum emission picture to calculate the signal [3], we provide numerical estimates of quantum reflection on dipole waves and other field configurations.
