标题： Nuclear-Spin Dependent Parity Violation in Optically Trapped Polyatomic Molecules

摘要： 我们研究使用光学捕获的线性多原子分子作为核自旋依赖性宇称不守恒的探测器。 这种分子普遍具有紧密间隔的相反宇称$\ell$-双峰，使得在通常比双原子分子小100倍的磁场中，可以将对宇称破坏敏感的能级对带入简并。 假设目前多原子分子的激光冷却和捕获技术达到双原子分子的最新水平，我们预计能够以比当前最佳测量高70倍的灵敏度测量核自旋依赖性宇称破坏矩阵元$iW$。 我们的方案应该允许对轻至铍或重至镱的核中的$iW$进行10%的测量，平均时间分别为约10天和1秒。 显示英文摘要

摘要： We investigate using optically trapped linear polyatomic molecules as probes of nuclear spin-dependent parity violation. The presence of closely spaced, opposite-parity $\ell$-doublets is a general feature of such molecules, allowing parity-violation-sensitive pairs of levels to be brought to degeneracy in magnetic fields typically 100 times smaller than in diatomics. Assuming laser cooling and trapping of polyatomics at the current state-of-the-art for diatomics, we expect to measure nuclear spin-dependent parity-violating matrix elements $iW$ with 70 times better sensitivity than the current best measurements. Our scheme should allow for 10 \% measurements of $iW$ in nuclei as light as Be or as heavy as Yb, with averaging times on order the of 10 days and 1 second, respectively.
