Two-frequency control and suppression of tunneling in the driven double well

Abstract

The effect of two-frequency driving of a symmetric double well is investigated classically and quantum mechanically. By computing Husimi distributions it is shown that control and suppression of tunneling may be achieved by driving the system with two fields whose frequencies are in a 1:2 ratio. In particular, a second field of finite duration can be used to selectively trap the wave packet in either well.
