Quantum and classical geometric phase of the time-dependent harmonic oscillator

Abstract

In a recent paper [Y. C. Ge and M. S. Child, Phys. Rev. Lett. 78, 2507 (1997)], by using a Gaussian wave function, Ge and Child presented a nonadiabatic relation between the quantum Berry phase and the classical Hannay angle for the time-dependent harmonic oscillator. In this paper, we present a perspective for this relation without the use of a trial wave function. In particular, an exact explicit formula for the cyclic evolution over the period T in the parameter space of action invariant is obtained; the -(n + 1/2) relation between the quantum geometric angle and the Hannay angle is rigorously established. ©2000 The American Physical Society.
