The National Science Foundation (NSF) awarded a $418,310 Project Grant under the Mathematical and Physical Sciences program (CFDA 47.049) to Temple University to theoretically model a novel molecular sensor system based on ultracold 223FrAg (francium-silver) molecules. The research aims to provide guidance for experimentalists to develop this sensor, which has the potential to detect symmetry-violating forces beyond the Standard Model of particle physics. The key products and services to be delivered include:

  1. Precise determination of the electronic states and radiative transition properties of the 223FrAg diatomic molecule using advanced relativistic computational methods.

  2. Numerical quantum scattering models to describe the formation of 223FrAg molecules from ultracold atoms under magnetic fields and laser radiation.

  3. Characterization of the light shifts on the 223FrAg molecular eigenstates, which is critical for mitigating systematic errors in precision measurements seeking small symmetry-breaking effects.

The 3-year project is scheduled to run from September 1, 2024 to August 31, 2027. No sub-awards are planned under this grant.
