We are building an experiment to search for the electron's electric dipole moment in laser-cooled and trapped polyatomic molecules.  These molecules offer robust systematic error rejection via internal co-magnetometer states, and provide a route to explore PeV-scale CP-violating physics.

YbOH rotational spectrum published in Chemical Physics Letters.

7 October 2018

We put a paper on the arXiv describing some measurements of the rotational structure of the YbOH ground state.  These measurements were performed at ASU using a supersonic beam of YbOH.
