关于Lewis-Riesenfeld(Dodonov-Man'ko)不变量方法

On the Lewis-Riesenfeld (Dodonov-Man'ko) invariant method

Julio Guerrero, Francisco F. López-Ruiz

摘要:

本文根据量子Arnold变换及其最近推广到量子Arnold-Ermakov-Pinney变换的结果,对求解量子含时谐振子的Lewis-Riesenfeld不变量方法进行了修正.我们证明了这两种方法是等价的,并显示了量子Arnold-Ermakov-Pinney变换的Lewis-Riesenfeld不变方法的优点。我们证明了在量子含时阻尼谐振子中,Dodonov和Man'ko提出的不变量更适用,并给出了一些例子来说明它,重点是阻尼的情况。

英文摘要:

We revise the Lewis-Riesenfeld invariant method for solving the quantum time-dependent harmonic oscillator in light of the Quantum Arnold Transformation previously introduced and its recent generalization to the Quantum Arnold-Ermakov-Pinney Transformation. We prove that both methods are equivalent and show the advantages of the Quantum Arnold-Ermakov-Pinney transformation over the Lewis-Riesenfeld invariant method. We show that, in the quantum time-dependent and damped harmonic oscillator, the invariant proposed by Dodonov & Man'ko is more suitable and provide some examples to illustrate it, focusing on the damped case.
