Is it possible to find the dynamics of a time-dependent system? For example, a harmonic oscillator that is driven by an external time-dependent drive? Does QuTip have a way to solve the Schrodinger equation for this time-dependent Hamiltonian in the absence of loss/dissipation? I understand that the dynamics may diverge but I want to simulate this system for the case of short-time driving. That is, I will turn the driving on and then off within a few cycles of the drive. Note: I do not want to use the Master equation for this. Is this possible?
