Seminar topic: “Electron dynamics in strong laser field”

Speaker: Suren Sukiasyan (YSU, Yerevan)

Abstract:

Numerical solution of the problem of one- and two-electron system dynamics in strong laser field is studied. In the first problem the role of the electron correlation in high-harmonic generation (HHG) process is investigated. Multi-Configuration Time-Dependent Hartree (MCTDH) method is utilized as a numerical tool for solving the problem. In the second task, the attosecond angular streaking (attoclock) is considered as a tool to investigate the tunneling time in intense laser field. An application to a simple system predicts a negative time shift for the electron passing through the tunneling barrier. In the third problem, the above-threshold ionization in the presence of transitions via intermediate bound states (Freeman resonances) for rare gases is studied using the single-electron approximation and compared with the experimental results.
