Highly Coherent Spectroscopy of Ultracold Atoms and Molecules in Optical Lattices (original) (raw)

Highly coherent spectroscopy of ultracold atoms and molecules in optical lattices has emerged as a pivotal area of research, harnessing the properties of two-electron atoms like strontium to realize new levels of precision in ultracold measurements. Such atoms offer simple interatomic potentials due to their lack of hyperfine structure, enabling enhanced manipulation of their quantum states and transition frequencies. The low magnetic moments allow for innovative cooling techniques, resulting in ground-metastable transitions with quality factors exceeding 10^18, which promises advancements in precision measurement and applications in quantum information and timekeeping.
