Vibrational branching fractions for laser cooling of Sr-containing nonlinear molecules

Paper by Alex and Zack (with collaborator Lan Cheng) has been featured in Editor’s Suggestion on PRA.

The authors explore candidates for a next-generation search for the electron electric dipole moment (eEDM) by experimentally measuring the vibrational loss channels in three Sr-containing nonlinear molecules. They conclude that SrNH2 is the optimal choice for a future laser-cooled molecule-based eEDM experiment.

Individual polyatomic molecules are trapped in optical tweezer arrays

Our results on an optical tweezer array of ultracold polyatomic molecules demonstrate control of polyatomic molecules (CaOH) at the single particle, single internal quantum state level. The ability to create and manipulate tweezer arrays of polyatomic molecules paves the way for a variety of experiments harnessing the rich structure of these molecules, including quantum simulation, quantum computation, and precision studies of ultracold collisions and chemistry.
