Directed selective tunneling of dipolar bosons in a driven triple well

We study the coherent control of quantum tunneling for dipolar bosons held in a driven triple-well potential. In the high-frequency region within the resonance case, based on the non-Floquet solutions of two dipolar bosons, the influence of dipolar interaction on tunneling is investigated analytically and numerically, in which the directed selective-tunneling of a single atom is demonstrated when the two bosons are located in the middle well initially. Further, the corresponding effect is exhibited numerically for more dipolar atoms N > 2 and the directed tunneling of 1 or (N - 1) atoms occurs by adjusting the driving parameters. These results may be useful in the design of atomic devices.
