修正振子的时间反演

The Time Inversion for Modified Oscillators

Ricardo Cordero-Soto, Sergei K. Suslov

摘要:

讨论了含时Schroedinger方程在变系数$R^n$中的一种新的完全可积情形,该情形是Meiler,Cordero-Soto和Suslov最近考虑的量子振子模型的时间反演的对偶.在动量表象中还发现了第二对对偶哈密顿量。我们的例子表明,在数学物理和量子力学中,时间方向的改变可能需要系统动力学的总体改变,以便使系统返回到其原始的量子态。也得到了相应的薛定谔方程的特解。讨论了经典可积问题的哈密顿结构及其量子化。

英文摘要:

We discuss a new completely integrable case of the time-dependent Schroedinger equation in $R^n$ with variable coefficients for a modified oscillator, which is dual with respect to the time inversion to a model of the quantum oscillator recently considered by Meiler, Cordero-Soto, and Suslov. A second pair of dual Hamiltonians is also found in the momentum representation. Our examples show that in mathematical physics and quantum mechanics a change in the direction of time may require a total change of the system dynamics in order to return the system back to its original quantum state. Particular solutions of the corresponding Schroedinger equations are also obtained. A Hamiltonian structure of the classical integrable problem and its quantization are also discussed.
