Laser-induced-continuum-structure (LICS) allows for coherent control techniques to be applied in a Raman type system with an intermediate continuum state. The standard LICS problem involves two bound states coupled to one or more continua. In this paper, we discuss the simplest non-trivial multistate generalization of LICS which couples two bound levels, each composed of two degenerate states through a common continuum state. We reduce the complexity of the system by switching to a rotated basis of the bound states, in which different sub-systems of lower dimension evolve independently. We derive the trapping condition and explore the dynamics of the sub-systems under different initial conditions.
激光诱导连续体结构(LICS)使得相干控制技术能够应用于具有中间连续体状态的拉曼型系统。标准的LICS问题涉及两个与一个或多个连续体耦合的束缚态。在本文中,我们讨论了LICS最简单的非平凡多态推广,它通过一个公共连续体状态耦合两个束缚能级,每个束缚能级由两个简并态组成。我们通过转换到束缚态的旋转基来降低系统的复杂性,在这个基中,不同的低维子系统独立演化。我们推导了俘获条件,并探索了不同初始条件下子系统的动力学。
