Construction of dynamical invariants for the time-dependent harmonic oscillator with a time-dependent driven force
arXiv:1409.2429
Abstract
We construct the linear and quadratic polynomial dynamical invariants for the classical and quantum time-dependent harmonic oscillator driven by a time-dependent force. To obtain them, we use exclusively the associated equations of motion for the system. We also find an algebraic relationship between the linear and quadratic invariants at the classical and quantum level.
