Amplitude and phase of time dependent Hamiltonian systems under the minimum uncertainty condition
G. Landolfi, G. Ruggeri, G. Soliani
We investigate dynamical systems with time-dependent mass and frequency, with particular attention on models attaining the minimum value of uncertainty formula. A criterium of mini…
