达布变换的推广与广义谐振子

Generalization of the Darboux transformation and generalized harmonic oscillators

Dae-Yup Song, John R. Klauder

摘要:

本文将Darbroux变换推广到包含动量线性项和质量随时间变化的含时哈密顿系统。的形式主义的$N$倍的应用程序的转换也建立,这些形式主义适用于一般的二次系统(广义谐振子)和二次系统的平方反比相互作用的N=2。在发现的新特征中,对于一般的二次系统,原系统和变换系统之间的电势差的形状可以按照经典解振荡,这与系统中相干态的存在有关.

英文摘要:

The Darbroux transformation is generalized for time-dependent Hamiltonian systems which include a term linear in momentum and a time-dependent mass. The formalism for the $N$-fold application of the transformation is also established, and these formalisms are applied for a general quadratic system (a generalized harmonic oscillator) and a quadratic system with an inverse-square interaction up to N=2. Among the new features found, it is shown, for the general quadratic system, that the shape of potential difference between the original system and the transformed system could oscillate according to a classical solution, which is related to the existence of coherent states in the system.
