Atomic systems with one and two active electrons in electromagnetic fields: Ionization and high harmonics generation

Abstract

We describe a theoretical procedure for solving the time-dependent Schrödinger equation (TDSE) for atomic systems with one or two valence electrons. Motion of the valence electrons is described by means of the Hartree-Fock potential including the exchange interaction. We apply the procedure to various physical phenomena occurring in atoms exposed to strong electromagnetic fields. As an illustration, we consider below the processes of high harmonics generation and attosecond pulses production. © 2010 IOP Publishing Ltd.
