Title: Revealing undiscovered forces using ultracold molecules
Abstract: Many experiments that use molecules in physics and chemistry could be hugely improved by cooling the molecules to ultracold temperatures, and this has sparked great interest in laser cooling of molecules. A particularly important measurement is the electron’s electric dipole moment (edm), where molecules provide key constraints on theories that extend the Standard Model of particle physics. A few molecular species were recently laser-cooled, but not yet heavy polar molecules, such as YbF, that are needed for edm searches and other precision measurements. In this talk, I will discuss recent success in sub-Doppler cooling of YbF, initiating a new era where ultracold molecules are used to test fundamental physics.
