What Is The Difference Between Time-independent And Time Dependent Perturbation Theory? In time-independent perturbation theory the perturbation Hamiltonian is static (i.e., possesses no time dependence). … The time-dependent amplitudes of those quantum states that are energy eigenkets (eigenvectors) in the unperturbed system. What is time dependent and time independent? Schrodinger’s time-independent wave equation describes the
