• 論文の詳細を見る

• Dynamical control of quantum tunneling in a coupled quantum well is predicted to occur when laser pulses drive sublevel transitions in one of the wells. The sublevel transition by the laser pulse induces phase change of the wave packets involved in the transition, which alters the successive evolutions of the wave packets, resulting in phase reversal of the tunneling oscillations and the inhibition of tunneling. It is also shown that complete tunneling oscillations can be realized, even between the nonresonant states, by means of a train of short pulses which has an appropriate pulse interval and pulse area.
