Electron dynamics in strong laser field

Seminar of the scientific department of computational physics

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), as a tool to investigate the tunneling time in intense laser field, is considered. 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 a presence of transitions via the intermediate bound states (Freeman resonances) for rare gases, using the single-electron approximation, is studied, and compared with the experimental results.
