Phenomenological rate formulas for over-barrier ionization of hydrogen and helium atoms in strong constant electric fields
S. Remme, A. B. Voitkiv, G. Pretzler +1
Nonrelativistic over-barrier ionization (OBI) of atoms in strong electric fields is studied, focussing on hydrogen and helium as concrete examples. Our goal is, on the one hand, to…

Entering the overcritical regime of nonlinear Breit-Wheeler pair production in collisions of bremsstrahlung -rays and superintense, tightly focused laser pulses
I. Elsner, A. Golub, S. Villalba-Chávez +1
Near-future high-intensity lasers offer prospects for the observation of nonlinear Breit-Wheeler pair production in an overcritical field regime, where the quantum nonlinearity par…
