标题： Transferring vibrational states of trapped atoms via a Rydberg electron

摘要： 我们从理论上展示，可以在相距微米的俘获中性原子之间相干地转移振动激发。 为此，我们考虑三个原子，其中两个处于电子基态，另一个被激发到一个与两个基态原子的位置波函数重叠的里德堡态。 里德堡电子与基态原子的散射提供了将振动激发从一个俘获原子转移到另一个所需的相互作用。 通过数值研究转移动力学对陷阱之间距离及其相对频率的依赖性，我们发现存在一个“最佳点”，在此处振动激发的转移几乎完美且比里德堡态寿命快得多。 我们研究了该情景在参数变化下的鲁棒性。 此外，我们推导了一个直观的有效哈密顿量，解释了观察到的动力学行为。 显示英文摘要

摘要： We show theoretically that it is possible to coherently transfer vibrational excitation between trapped neutral atoms over a micrometer apart. To this end we consider three atoms, where two are in the electronic ground state and one is excited to a Rydberg state whose electronic orbital overlaps with the positional wave functions of the two ground-state atoms. The resulting scattering of the Rydberg electron with the ground-state atoms provides the interaction required to transfer vibrational excitation from one trapped atom to the other. By numerically investigating the dependence of the transfer dynamics on the distance between traps and their relative frequencies we find that there is a "sweet spot" where the transfer of a vibrational excitation is nearly perfect and fast compared to the Rydberg lifetime. We investigate the robustness of this scenario with respect to changes of the parameters. In addition, we derive a intuitive effective Hamiltonian which explains the observed dynamics.
