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
Solution of time-dependent harmonic oscillator system using explicit Euler method and discussion of the cyclic initial states
【摘要】 利用IoanSturzu提出的explicitEuler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 .
【Abstract】 The Schrdinger equation of forced time-dependent harmonic oscillator is solve d by using the explicit Euler method. The result of evolution of the initial sta te is given, the feasibility and applicability of explicit Euler method are disc ussed. Using coherent state, the non-adiabatic berry phase and the cyclic initi al states of the system are discussed.
