Collective tunnel ionization in atomic systems
D. I. Tyurin, V. V. Strelkov, S. V. Popruzhenko
We present a theory of the collective tunnel effect in atomic systems subject to strong low-frequency laser fields. Using an analytic semi-classical method and numerical solution t…

Breakdown of sequential tunnel ionization in ultrashort electromagnetic pulses
D. I. Tyurin, V. V. Strelkov, S. V. Popruzhenko
We consider double ionization of negative bromine ion in intense low-frequency electromagnetic fields. By solving numerically the two-electron time-dependent Schr{\" o}dinger equat…
