论文摘要
我们通过S-Wave Feshbach共振在864.11（5）g中通过磁递增来证明了光镊中单个NACS分子的形成。从冷却到其运动基态的单个原子开始，我们达到47（1）％的转化效率，并测量分子寿命为4.7（7）ms。根据构造，单分子在镊子的质量中心运动基态中主要是（77（5）％）。此外，我们通过先制备一种具有一个量子的运动激发的原子来产生一个接近807g的单个P波分子。我们在光学镊子的运动基态下在指定的内部状态下创建单个弱结合的分子是朝着光学镊子阵列中单分子相干控制的关键步骤。
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 807G 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.
