论文摘要
我们提出了一个方案，以实现从超电原子的气体中实现一对绑定的一对相对充满电的离子的重型Rydberg系统（HRS）。实现大核对间分离的中间步骤是创建在楼梯间势能曲线中结合的独特的超长范围rydberg分子。在这里，由于吸引人的单线$ p $ - 波散射，地下原子与振荡电势的rydberg原子绑定在一起。我们方法的效用源于rydberg-和离子分子之间的大型电子偶极转变元件，而维定了超速气体的核构型。 Rydberg分子和重型Rydberg系统之间的Rabi耦合通常在MHz范围内，HRS的永久性电偶极矩可以与一公斤一样大。我们确定特定的过渡，这些过渡将重型Rydberg系统的创建置于实验实现的立即范围内。
We propose a scheme to realize a heavy Rydberg system (HRS), a bound pair of oppositely charged ions, from a gas of ultracold atoms. The intermediate step to achieve large internuclear separations is the creation of a unique class of ultra-long-range Rydberg molecules bound in a stairwell potential energy curve. Here, a ground-state atom is bound to a Rydberg atom in an oscillatory potential emerging due to attractive singlet $p$-wave electron scattering. The utility of our approach originates in the large electronic dipole transition element between the Rydberg- and the ionic molecule, while the nuclear configuration of the ultracold gas is preserved. The Rabi coupling between the Rydberg molecule and the heavy Rydberg system is typically in the MHz range and the permanent electric dipole moments of the HRS can be as large as one kilo-Debye. We identify specific transitions which place the creation of the heavy Rydberg system within immediate reach of experimental realization.
