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…
Role of plasma waves in rescattering processes in intense laser fields
V. V. Strelkov, S. A. Bondarenko, I. V. Smetanin
Rescattering of the photoelectron at its parent ion underlie a number of phenomena in intense laser field interaction with matter, such as high harmonic generation, attosecond puls…
Fano resonance in XUV generated by helium with few-cycle intense laser pulses and its classical analogy
S. A. Bondarenko, V. V. Strelkov
We integrate numerically the Schrödinger equation for the model helium atom irradiated by intense few-cycle laser pulse and find the emitted XUV spectra. They demonstrate resonant…
