Precision Control of Ultracold Molecules in Optical Lattices
Abstract
During the reported period robust and sensitive techniques to produce and control ultracold polar KRb and RbCs as well as homonuclear Cs2 and Sr2 molecules have been developed. Factors that affect precision measurements and many-body quantum-collective experiments with these molecules have been analyzed. As part of these efforts the coherent transfer between weakly-bound Feshbach molecules and ro-vibrational ground state have been studied. In particular, high-precision calculations of the electronic potentials and transition dipole moments have been performed. Moreover, models for precision measurement of time variation of the proton-to-electron mass ratio using ultracold molecules in an optical lattice have been investigated by developing a zero-differential-Stark-shift optical lattice technique. The analyses included calculations of the molecular vibrational structure, lifetime of excited states, and Stark shifts of vibrational levels. Other accomplishments were the development of ab-initio methods for structural analysis of relativistic effects in heavy alkali-metal RbCs and Cs2 molecules. The research resulted in fifteen papers in refereed journals.
