Strontium molecular clock for physics searches beyond the Standard Model

We present a Sr₂ molecular lattice clock and describe its unique opportunities as a precision measurement platform. This includes supplying the most precise frequency reference in the THz frequency range and providing the ability to constrain non-Newtonian gravity at ultrashort range. We are working toward a vibrational isotope shift measurement in order to place constraints on Yukawa-type mass-dependent forces at the nanometer scale. Here we discuss progress toward producing the ⁸⁶Sr₂ isotopologue at ultracold temperatures, including addressing isotope shifts for cooling and trapping atoms, and photoassociating the molecules. We also discuss implementation of a new lattice configuration to reduce lattice light scattering and reactive collisions to improve the clock precision.
