Pulsating States for Quantal Harmonic Oscillator
I. Fujiwara, K. Miyoshi · Progress of Theoretical Physics · 1980
In contrast to its coherent state, the quantal harmonic oscillator allows the existence of another state of completely nonclassical character. It is represented by a Gaussian wave packet, of which the center remains at rest and the width varies sinusoidally with time. Thus we may term it pulsating state.
