用explicit Euler 方法研究含时受迫谐振子的演化及对系统循环初态的讨论

利用Ioan Sturzu 提出的explicit Euler方法 (EEM) 计算了含时受迫谐振子的系统初态随时间的演化及概率分布规律，分析了EEM的可行性及适用性，并由相干态讨论了受迫谐振子系统循环初态的存在条件以及非绝热几何相. 关键词： explicit Euler 方法 含时受迫谐振子 循环初态 非绝热几何相

Solution of time-dependent harmonic oscillator system using explicit Euler method and discussion of the cyclic initial states

The Schrdinger equation of forced time dependent harmonic oscillator is solved by using the explicit Euler method. The result of evolution of the initial state is given, the feasibility and applicability of explicit Euler method are discussed. Using coherent state, the non adiabatic berry phase and the cyclic initial states of the system are discussed.
