我们提出了一个精确控制偶极玻色子在三势阱中隧穿动力学的方案。在高频制度和共振条件下,我们已经分析和数值证明,我们可以通过调整驱动参数沿着不同的路径和在不同的方向上传输一个先验的规定数量的偶极玻色子。这些结果扩展了先前在双阱势中非偶极玻色子的隧穿方案的多体选择性相干破坏(Gong等人2009 Phys. Rev. Lett. 103 133002; Longhi 2012 Phys.Rev.A86 044102),从而提供了设计远程相干量子传输的有效方式。
We propose a scheme for precise control of the tunneling dynamics of dipolar bosons in shaken triple-well potentials. In high-frequency regimes and under resonance conditions, we have analytically and numerically demonstrated that we can transport an a priori prescribed number of dipolar bosons along different pathways and in different directions by adjusting the driving parameters. These results extend the previous many-body selective coherent destruction of tunneling schemes for nondipolar bosons in double-well potentials (Gong et al 2009 Phys. Rev. Lett. 103 133002; Longhi 2012 Phys. Rev. A 86 044102), thus offering an efficient way to design long-range coherent quantum transportation.
