Bound-free electron-positron pair production in combined Coulomb and constant crossed electromagnetic fields: a Schwinger-like process with intrinsic assistance
S. Remme, A. Eckey, S. Villalba-Chávez +4
The bound-free channel of electron-positron pair production by a highly charged bare ion in the presence of a strong constant crossed electromagnetic field is studied. To calculate…

Ionization of atoms by dense and compact beams of extreme relativistic electrons
S. Kim, C. Müller, A. B. Voitkiv
Ionization is one of the basic physical processes, occurring when charged particles penetrate atomic matter. When atoms are bombarded by very dense and compact beams of extreme rel…

Relative-phase dependence of dynamically assisted electron-positron pair creation in the superposition of strong oscillating electric-field pulses
J. BraÃ, D. M. Müller, S. Villalba-Chávez +2
Production of electron-positron pairs in the superposition of oscillating electric-field pulses with largely different frequencies is studied, focussing on the impact of relative p…
