“…For example, experiments using stable, dynamically octupole-deformed 153 Eu 3+ ions embedded in a crystal are under development, with anticipated sensitivity to CP-violating physics several orders of magnitude beyond current bounds. 211,212 Octupole deformation in Dy has also been established by thorough experimental and theoretical studies, 213 and the stable and naturally abundant 161 Dy nucleus is expected to possess a large NSM. 121 Dy-containing piezoelectric solids have already been proposed to probe oscillatory Schiff moments induced by QCD axion dark matter.…”

Relativistic exact two-component coupled-cluster calculations of molecular sensitivity factors for nuclear Schiff moments (NSMs) are reported. We focus on molecules containing heavy nuclei, especially octupole-deformed nuclei. Analytic relativistic coupledcluster gradient techniques are used and serve as useful tools for identifying candidate molecules that sensitively probe for physics beyond the Standard Model in the hadronic sector. Notably, these tools enable straightforward "black-box" calculations. Two competing chemical mechanisms that contribute to the NSM are analyzed, illuminating the physics of ligand effects on NSM sensitivity factors.

“…This fact has led to experimental proposals to measure the MQM using molecules like YbF [20] and YbOH [21,22], exploiting the internal magnetic field gradient induced by the electric field in polarized molecules. Recently, MQM measurements using solids containing deformed nuclei have also been proposed [23][24][25].…”

We propose a scheme to measure a nuclear magnetic quadrupole moment (MQM), a CP-violating electromagnetic moment that appears in the nuclear sector, using the long-lived 3P2 metastable state in neutral 173Yb atoms. Laser-cooling and trapping techniques enable us to prepare ultracold 173Yb atoms in the 3P2 state trapped in an optical lattice or an optical tweezer array, providing an ideal experimental platform with long spin coherence time. In addition, our relativistic configuration interaction calculation for the 3P2 electronic wavefunction reveals a large magnetic field gradient generated by the atomic electrons in this state, which amplifies the measurable effect of an MQM. Our scheme could lead to an improvement of more than one order of magnitude in MQM sensitivity compared to the best previous measurement [S. A. Murthy et al., Phys. Rev. Lett. 63, 965 (1989)].
