Strong-field QED in Furry-picture momentum-space formulation: Ward identities and Feynman diagrams
Uwe Hernandez Acosta, Burkhard Kämpfer
The impact of a strong electromagnetic background field on otherwise perturbative QED processes is studied in the momentum-space formulation. The univariate background field is ass…
Positron energy distribution in factorized trident process
A. I. Titov, U. Hernandez Acosta, B. Kampfer
We estimate the energy distribution of positrons produced in the interaction of ultra-relativistic electrons with a high-intensity laser beam. The underlying trident process is fac…
Rise and fall of laser-intensity effects in spectrally resolved Compton process
Uwe Hernandez Acosta, Alexander I. Titov, Burkhard Kämpfer
The spectrally resolved differential cross section of Compton scattering, , rises from small towards larger laser intensity parameter , reaches a m…
Non-perturbative signatures of non-linear Compton scattering
Uwe Hernandez Acosta, Andreas Otto, Burkhard Kämpfer +1
The probabilities of various elementary laser - photon - electron/positron interactions display in selected phase space and parameter regions typical non-perturbative dependencies…
Laser pulse-length effects in trident pair production
Uwe Hernandez Acosta, Burkhard Kämpfer
Laser pulses facilitate multiphoton contributions to the trident pair production , where the label indicates a laser field dressed electron ($…
