Production of ultracold asymmetric tops from Sr atoms and SrOH molecules

Abstract

We report the comprehensive theoretical investigation of the Sr–SrOH system identifying it as a promising route to production of ultracold asymmetric top molecules. Combining high-level ab initio electronic structure calculations with rigorous quantum scattering simulations, we determine strongly anisotropic, non-reactive interaction potential and an exceptionally dense spectrum of near-threshold resonances. Presented excited states, transition dipole moments, and results of the one-dimensional STIRAP model suggest the possibility of coherently transferring weakly bound complexes to the rovibrational ground state.
