同时具有电子自旋和电偶极矩的超冷分子为量子科学提供了新的可能性。我们使用密度泛函理论计算了该领域重要分子的超精细耦合常数，包括RbSr， LiYb, RbYb， CaF和SrF。我们发现了碱土金属和镱原子的费米子同位素的大量超精细耦合常数。我们讨论了这些分子的超精细能级模式和塞曼分裂。这一结果对于旨在形成超冷开壳分子的实验及其应用具有重要意义。
Ultracold molecules with both electron spin and an electric dipole moment offer new possibilities in quantum science. We use density-functional theory to calculate hyperfine coupling constants for a selection of molecules important in this area, including RbSr, LiYb, RbYb, CaF, and SrF. We find substantial hyperfine coupling constants for the fermionic isotopes of the alkaline-earth-metal and Yb atoms. We discuss the hyperfine level patterns and Zeeman splittings expected for these molecules. The results will be important both to experiments aimed at forming ultracold open-shell molecules and to their applications.
