Resonances in the continuum, field induced nonstationary states, and the state and property specific treatment of the many electron problem

Abstract

The paper summarizes elements of theories and computational methods that we have constructed and applied over the years for the nonperturbative solution of many electron problems, in the absence or presence of strong external fields, concerning resonance and nonstationary states with a variety of electronic structures.
