Abstract: Ultracold atom technologies have transformed our ability to perform high-precision spectroscopy and apply it to time and frequency metrology. Many of the highest-performing atomic clocks are based on laser-cooled atoms trapped in optical lattices. These clocks can be applied to fundamental questions, for example to improve our understanding of gravity and general relativity. In this talk, I will discuss using lattice-trapped ultracold diatomic molecules, rather than atoms, as a reference for clocks. Molecules have more internal quantum states and therefore are relatively challenging to control. On the other hand, their vibrational modes offer a large number of prospective clock transitions that can help us probe alternative aspects of new physical interactions. I will discuss the current precision limitations of molecular metrology and possible paths forward.
