Nuclear magnetic quadrupole moments (MQMs), such as intrinsic electric dipole moments of elementary particles, violate both parity and time-reversal symmetry and, therefore, probe physics beyond the standard model. We report on accurate relativistic coupled cluster calculations of the nuclear MQM interaction constants in BaF, YbF, BaOH, and YbOH. We elaborate on estimates of the uncertainty of our results. The implications of experiments searching for nonzero nuclear MQMs are discussed.
核磁四极矩（MQMs），例如基本粒子的内禀电偶极矩，违反宇称和时间反演对称性，因此，可用于探索超出标准模型的物理学。我们报告了对BaF、YbF、BaOH和YbOH中核磁四极矩相互作用常数的精确相对论耦合簇计算。我们详细阐述了结果不确定性的估计。讨论了寻找非零核磁四极矩的实验的意义。
