Abstract
Clocks that are based on atomic and molecular transitions can serve as unparalleled sensors of fundamental phenomena. In particular, a clock based on vibrations in a diatomic molecule is a highly precise sensor of the interatomic force, including possible contributions from new physics. Such a clock is also of metrological interest, since vibrational states in homonuclear molecules have extremely long lifetimes. We present the technique of near-resonant magic-wavelength trapping for strontium dimers, which allows us to reach coherence times exceeding 100 ms for far-separated vibrational state superpositions. The development of the molecular clock is accelerated through state-of-the-art quantum chemistry work.
