我们探索了通过二次核价电子的光学修饰将碱土里德堡原子限制在光学晶格中的前景。聚焦于锶的特殊情况，我们确定了实验上可用来同时俘获基态和里德堡态的魔波。对相关损耗机制的详细分析表明，这种系统的总寿命仅受里德堡态自发衰变的限制，而不受光致电离或自电离的显著影响。计算了Sr(5Sns1S0)Rydberg系列的范德华C6系数，发现相互作用是吸引的。最后，我们证明了魔波晶格和吸引相互作用的结合可以被用来产生多体Greenberger-Horne-Zeilinger态。
We explore the prospects for confining alkaline-earth Rydberg atoms in an optical lattice via optical dressing of the secondary core–valence electron. Focussing on the particular case of strontium, we identify experimentally accessible magic wavelengths for simultaneous trapping of ground and Rydberg states. A detailed analysis of relevant loss mechanisms shows that the overall lifetime of such a system is limited only by the spontaneous decay of the Rydberg state, and is not significantly affected by photoionization or autoionization. The van der Waals C6 coefficients for the Sr(5sns 1S0) Rydberg series are calculated, and we find that the interactions are attractive. Finally we show that the combination of magic-wavelength lattices and attractive interactions could be exploited to generate many-body Greenberger–Horne–Zeilinger states.
