| Abstract: | A VIRTUAL AMO SEMINAR presented in a Zoom meeting vetted by CQuIC. See https://sites.google.com/stanford.edu/virtual-amo-seminar/schedule for the meeting link. The close spacing of opposite-parity levels in molecules enhances the effects of parity-violating fundamental interactions. I will discuss results from two recent experiments probing such interactions. The first, ACME II, sets the tightest bound on the electron's electric dipole moment. This result yields information on new CP-violating physics at energy scales far above the reach of the Large Hadron Collider. The second experiment, ZOMBIES, is designed to measure anapole moments of nuclei. A nuclear anapole moment arises from electroweak interactions within the nucleus, which are heavily modified in the presence of strong interactions and remain poorly understood. As a proof of principle, ZOMBIES recently demonstrated sensitivity roughly 7 times better than the best prior anapole moment measurements. Finally, I will discuss ongoing efforts and future prospects for dramatic improvements in sensitivity to these and other, related effects. | |
