Impact of background field localization on vacuum polarization effects
Carl Marmier, Nico Seegert, Felix Karbstein
We aim at insights about how localization of the background field impacts nonlinear quantum vacuum signatures probed by photons in purely magnetic, electric and crossed fields. The…
Photon merging and splitting in electromagnetic field inhomogeneities
Holger Gies, Felix Karbstein, Nico Seegert
We investigate photon merging and splitting processes in inhomogeneous, slowly varying electromagnetic fields. Our study is based on the three-photon polarization tensor following…
Quantum reflection of photons off spatio-temporal electromagnetic field inhomogeneities
Holger Gies, Felix Karbstein, Nico Seegert
We reconsider the recently proposed nonlinear QED effect of quantum reflection of photons off an inhomogeneous strong-field region. We present new results for strong fields varying…
Quantum Reflection as a New Signature of Quantum Vacuum Nonlinearity
Holger Gies, Felix Karbstein, Nico Seegert
We show that photons subject to a spatially inhomogeneous electromagnetic field can experience quantum reflection. Based on this observation, we propose quantum reflection as a nov…
