我们证明了在光镊中通过864.11（5）G的s波Feshbach共振通过磁缔合形成单个NaCs分子。从冷却到运动基态的单个原子开始，我们实现了47（1）%的转换效率，并测量了4.7（7）ms的分子寿命。通过构建，单个分子主要处于镊子的质心运动基态[77（5）%]。此外，我们产生一个单一的p波分子附近807 G的第一次准备一个原子与一个量子的运动激发。我们创建一个单一的弱结合的分子在一个指定的内部状态中的运动基态的光镊是一个关键的一步，在光镊阵列中的单分子相干控制。
We demonstrate the formation of a single NaCs molecule in an optical tweezer by magnetoassociation through an s-wave Feshbach resonance at 864.11(5) G. Starting from single atoms cooled to their motional ground states, we achieve conversion efficiencies of 47(1)%, and measure a molecular lifetime of 4.7(7) ms. By construction, the single molecules are predominantly [77(5)%] in the center-of-mass motional ground state of the tweezer. Furthermore, we produce a single p-wave molecule near 807 G by first preparing one of the atoms with one quantum of motional excitation. Our creation of a single weakly bound molecule in a designated internal state in the motional ground state of an optical tweezer is a crucial step towards coherent control of single molecules in optical tweezer arrays.
