Yf. Liu et al., Angular momentum and energy structure of the coherent state of a 2D isotropic harmonic oscillator, COMM TH PHY, 33(3), 2000, pp. 487-490
The angular momentum structure and energy structure of the coherent state o
f a 2D isotropic harmonic oscillator were investigated. Calculations showed
that the average values of angular momentum and energy (except the aero-po
int energy) of this nonspreading 2D wavepacket are identical to those of th
e corresponding classical oscillator moving along a circular or an elliptic
orbit.
