Ionization dynamics of extended multielectron systems

摘要: Ionization of multielectron systems is investigated by using one-dimensional, multiconfiguration time-dependent Hartree-Fock calculations. Our analysis reveals the key physical processes underlying ionization complex systems. The laser-induced dynamics, and therewith process, depend on ratio laser frequency ({omega}{sub 0}) to plasmon p}). In overresonant limit 0}>>{omega}{sub p}), tunnel destroyed takes place a classical over barrier mechanism. underresonant regime 0}<<{omega}{sub remains dominant, but weakened polarization-induced growth tunneling barrier.
