Multilevel Laser Induced Continuum Structure

Abstract
Laser-induced-continuum-structure(LICS) allows for coherent control techniques to be applied in a Raman type system with intermediate continuum state. To this end the standard LICS problem treats two bound states coupled to one or more continua states. In this paper we discuss the simplest non-trivial multilevel generalization of LICS coupling two bound levels, each composed of two degenerate states through a common continuum state. We reduce the complexity of the effective system of bound states by switching to a rotated basis in which different sub-systems of lower dimension evolve independently. We derive a trapping condition and explore the dynamics of the sub-systems under different initial conditions.
