提出了一种用外场控制非绝热相变的新思想。其基本原理是周期性地扫描每个能级交叉处的外场,以使从初始状态到任何理想最终状态的总跃迁概率等于1。最近完成的非绝热相变的半经典理论使我们能够解析地处理这个问题。本思想可适用于各种物理和化学问题,只要水平交叉口是由一个外部领域。[S0031-9007(98)07054-9]
A new idea of controlling nonadiabatic transitions by an external field is proposed. The basicprinciple is to periodically sweep an external field at each level crossing to make the overall transitionprobability from an initial state to any desirable final state equal to unity. The recently completedsemiclassical theory of nonadiabatic transition enables us to analytically deal with this problem. Thepresent idea may be applicable to various physical and chemical problems, whenever level crossings arecreated by an external field. [S0031-9007(98)07054-9]
