Sensing parity-violation effects in chiral molecular ions:

ORAL

Abstract

The search for parity-violation (PV) effects pushes the boundaries of the standard model. It was predicted [1] that the PV effects disrupt the left-right symmetry and induce energy variations in chiral molecules. However, direct and strong experimental evidence still eludes to date. In the presentation, we will report integrated theoretical efforts to guide the potential experimental endeavors for sensing PV effects with the trapped molecular ion experiment technique[2]. The resolution of the molecular energy levels, including the hyperfine interactions and the molecular Stark shift associated with the ion trap, and the design of the experimental state preparation protocols will be discussed. We expect that the proposed approach, by leveraging the molecular degrees of freedom and by performing precise control of the quantum state of a trapped molecular ion, will lead to promising PV effects measurement in the near future.
