Abstract

We use the Lewis and Riesenfeld invariant method to obtain the exact Schr"odinger wave functions for a time-dependent harmonic oscillator with and without an inverse quadratic potential. As a particular case we also obtain the wave functions for the Caldirola-Kanai oscillator.

Exact Schrödinger wavefunctions ofN-coupled time-dependent harmonic oscillators

Min-Ho Lee

For N -coupled time-dependent harmonic oscillators with any couplings coordinates and momentum, we have derived the primary invariant and the generalized (Lewis and Riesenfeld) invariant represented in terms of the classical solution matrix of Hamilton's oscillator equation. Using the Lewis and Riesenfeld invariant method and exploiting the properties of the symplectic matrix we have obtained the exact Schrödinger wavefunctions for the oscillators.

A class of exactly solved time-dependent quantum harmonic oscillators

Sang Pyo Kim

We consider a class of time-dependent harmonic oscillators, H(t)=p 2 /2mt alpha + m omega 2 t b q 2 /2, whose mass and frequency vary as non-negative powers of time. Classically they describe damping oscillators slowly decaying as negative powers of time. Using the connection between classical and quantum harmonic oscillators we find analytically the Lewis-Riesenfeld invariants, obtain the exact quantum states, and compare these with the Caldirola-Kanai oscillator.
