Exploring new physics with Molecular Ions

The electron's electric dipole moment (eEDM)/Nuclear Magnetic Quadruple Moment (NMQM) are quantities that allows for an explanation for events such as the matter antimatter imbalance and odd Charge Parity violations. While, current measurements of the eEDM have not definitively proven the existence of eEDM, the information gained through precision measurements has already constrained many extension theories. We plan to further increase precision of the measurement of eEDM using three different technologies (1) the large internal electric field of the molecular ion, TaO+ to enhance the energy shift cause by eEDM; (2) A Quantum Logic Scheme to prepare and readout a quantum state with unit certainty in a static frame; (3) a segmented ring ion trap to confine a single TaO+ molecular ion in a circular potential, and apply a rotating electric field. The expected precision of our measurement is 10^-31 e.cm. The segmented ring trap design will also use for investigation of cold ion radical collisions.
