论文摘要
我们通过刺激的拉曼绝热通道（Raman Dibatic Passage）报告了在其绝对反振动基态中的玻色粒NACS分子的产生。我们在300（50）NK的温度下创建最高22,000个偶极NACS分子的超速气体，峰值密度为$ 1.0（4）\ times 10^{12} $ cm $ $^{ - 3} $。我们通过在特定的电子，振动，旋转和超细状态的特定分子中制备分子来证明全面的量子状态控制。使用NACS的永久性电偶极矩的可调性和强度，我们诱导了高达2.6的D. NACS分子的偶极系统的偶极矩，非常适合探索偶极量子物质中强烈相互作用的相。
We report on the creation of bosonic NaCs molecules in their absolute rovibrational ground state via stimulated Raman adiabatic passage. We create ultracold gases with up to 22,000 dipolar NaCs molecules at a temperature of 300(50) nK and a peak density of $1.0(4) \times 10^{12}$ cm$^{-3}$. We demonstrate comprehensive quantum state control by preparing the molecules in a specific electronic, vibrational, rotational, and hyperfine state. Employing the tunability and strength of the permanent electric dipole moment of NaCs, we induce dipole moments of up to 2.6 D. Dipolar systems of NaCs molecules are uniquely suited to explore strongly interacting phases in dipolar quantum matter.
