Ultracold molecular physics with strontium dimers
High-precision spectroscopy has been instrumental in the progress of atomic physics. In this talk, we extend precision spectroscopy techniques to ultracold diatomic strontium molecules trapped in an optical lattice, and discuss experimental results and from the point of view of molecular and fundamental science. For weakly bound molecules near the atomic threshold corresponding to the narrow intercombination transition, we observe peculiar and unexpected physics, including anomalously large linear and quadratic Zeeman shifts, and strongly forbidden transitions. We also study ground state molecules and discuss the present status of the molecular lattice clock and the physics it is able to probe.
