Heisenberg-picture approach to the exact quantum motion of a time-dependent forced harmonic oscillator
Hyeong-Chan Kim, Minho Lee, Jeong‐Young Ji, Jae Kwan Kim
Abstract
In the Heisenberg picture, the generalized invariant and exact quantum motions are found for a time dependent forced harmonic oscillator. We find the eigenstate and the coherent state of the invariant and show that the dispersions of these quantum states do not depend on the external force. Our formalism is applied to two interesting cases. \textcopyright{} 1996 The American Physical Society.
