Complete population transfer between nonresonant tunneling states induced by a train of laser pulses

Complete population transfer between nonresonant tunneling states in a doub le-well system is predicted to occur when a train of bright or dark laser p ulses drives transitions to an excited state in the system. The transition induces the phase shift of the wave packet involved in the transition and a lters successive evolutions of the wave packets of the nonresonant states a s a result of quantum interference, resulting in complete tunneling.
