Abstract
So far, we have considered only time-independent and periodic time-dependent perturbations. One of the common time-dependent problems in quantum mechanics involves the turning on or off of a perturbing term, e.g., an external field. In general, the details of turning on or off of time-dependent perturbations are too difficult to solve. Two limiting cases exist, however, that are both important and that can be treated in detail with good accuracy: the sudden and the adiabatic approximations.
