Abstract
The study of ultracold molecules tightly trapped in an optical lattice can expand the frontier of precision measurement and spectroscopy, and provide a deeper insight into molecular and fundamental physics. Here we create, probe, and image microkelvin 88Sr2 molecules in a lattice, and demonstrate precise measurements of molecular parameters as well as coherent control of molecular quantum states using optical fields. We discuss the sensitivity of the system to dimensional effects, a new bound-to-continuum spectroscopy technique for highly accurate binding energy measurements, and prospects for new physics with this rich experimental system.
Highlights
Many of the concepts and methods that emerged from research with ultracold atoms are gaining traction with more complex physical systems
We demonstrate a combination of light-assisted molecule formation [1] with optical lattice clock techniques [2,3,4] that yields optical and microwave spectra of molecules with unprecedented resolution
The transition strength measurements are in good agreement with a state-of-the-art ab initio quantum chemistry model [6], and are essential for designing efficient molecule formation pathways, as well as for refining the toolkit of ab initio molecular calculations
