Effects of an Oscillating Electric Field on and Dipole Moment Measurement of a Single Molecular Ion

May 31, 2023

Author(s)

Alejandra Collopy, Julian Schmidt, Dietrich Leibfried, David Leibrandt, Chin-wen Chou

We characterize and model the Stark effect due to the radio-frequency (rf) electric field experienced by a molecular ion in an rf Paul trap, a leading systematic in the uncertainty of the field-free rotational transition. The ion is deliberately displaced

Frequency-comb spectroscopy on pure quantum states of a single molecular ion

March 27, 2020

Author(s)

Chin-wen Chou, Alejandra L. Collopy, Christoph Kurz, Yiheng Lin, Michael E. Harding, Philipp N. Plessow, Tara M. Fortier, Scott A. Diddams, Dietrich G. Leibfried, David R. Leibrandt

Spectroscopy is a powerful tool for studying molecular properties and is commonly performed on large thermal ensembles of molecules that are perturbed by motional shifts and interactions with the environment and one another, resulting in convoluted spectra
