ABSTRACT

Revelation of the underlying physical basis of wave packet focusing; Corodinate-dependent two-level-system approximation employed to further analyze the molecular dynamics induced by short laser pulses.

    We use the Kramers-Henneberger approximation to investigate the phenomenon of stabilization of quantum systems with short-range potentials in a strong electromagnetic field. We identify the physical limits imposed on our investigation by the use of this approximation, and the ranges of parameter...
