DYNAMICS OF GENERALIZED COHERENT STATES
S. De Martino, Silvio De Siena, Fabrizio Illuminati · Modern Physics Letters B · 1995
We show that generalized coherent states follow Schrödinger dynamics in time-dependent potentials. The normalized wave-packets follow a classical evolution without spreading; in turn, the Schrödinger potential depends on the state through the classical trajectory. This feedback mechanism with continuous dynamical re-adjustment allows the packets to remain coherent indefinitely.
