Ergodicity breaking in rapidly rotating C60 fullerenes
Lee R. Liu, Dina Rosenberg, P. Bryan Changala +5
Ergodicity, the central tenet of statistical mechanics, requires that an isolated system will explore all of its available phase space permitted by energetic and symmetry constrain…
High resolution photoassociation spectroscopy of the excited potential of NaCs
Lewis R. B. Picard, Jessie T. Zhang, William B. Cairncross +8
We report on photoassociation spectroscopy probing the potential of the bi-alkali NaCs molecule, identifying eleven vibrational lines between and of…
Collision-induced C_60 rovibrational relaxation probed by state-resolved nonlinear spectroscopy
Lee R. Liu, P. Bryan Changala, Marissa L. Weichman +6
Quantum state-resolved spectroscopy was recently achieved for C60 molecules when cooled by buffer gas collisions and probed with a midinfrared frequency comb. This rovibrational qu…
Multichannel interactions of two atoms in an optical tweezer
Jonathan D. Hood, Yichao Yu, Yen-Wei Lin +5
The multichannel Na-Cs interactions are characterized by a series of measurements using two atoms in an optical tweezer, along with a multichannel quantum defect theory (MQDT). The…
Molecular assembly of ground state cooled single atoms
Lee R. Liu, Jonathan D. Hood, Yichao Yu +5
We demonstrate full quantum state control of two species of single atoms using optical tweezers and assemble the atoms into a molecule. Our demonstration includes 3D ground-state c…
Building one molecule from a reservoir of two atoms
L. R. Liu, J. D. Hood, Y. Yu +4
Chemical reactions typically proceed via stochastic encounters between reactants. Going beyond this paradigm, we combine exactly two atoms into a single, controlled reaction. The e…
Motional Ground State Cooling Outside the Lamb-Dicke Regime
Yichao Yu, Nicholas R. Hutzler, Jessie T. Zhang +4
We report Raman sideband cooling of a single sodium atom to its three-dimensional motional ground state in an optical tweezer. Despite a large Lamb-Dicke parameter, high initial te…
Ultracold Molecular Assembly
Lee R. Liu, Jessie T. Zhang, Yichao Yu +4
Chemical reactions can be surprisingly efficient at ultracold temperatures ( < 1mK) due to the wave nature of atoms and molecules. The study of reactions in the ultracold regime is…
Eliminating light shifts in single-atom optical traps
Nicholas R. Hutzler, Lee R. Liu, Yichao Yu +1
Microscopically controlled neutral atoms in optical tweezers and lattices have led to exciting advances in the study of quantum information and quantum many-body systems. The light…
