Direct observation of ultracold molecular reactions
TL;DR: In this paper, the authors used ionization spectroscopy and velocity-map imaging (VMI) of a trapped gas of potassium-rubidium molecules at a temperature of 500~nK to observe reactants, intermediates, and products of the four-center reaction.

Multichannel interactions of two atoms in an optical tweezer
J. D. Hood,J. D. Hood,Yichao Yu,Yichao Yu,Yen-Wei Lin,Yen-Wei Lin,Jessie T. Zhang,Jessie T. Zhang,Kenneth Wang,Kenneth Wang,Lee R. Liu,Lee R. Liu,Bo Gao,Kang-Kuen Ni,Kang-Kuen Ni +14 more
TL;DR: In this article, a series of measurements using two atoms in an optical tweezer, along with a multichannel quantum defect theory (MQDT), along with the triplet and singlet scattering lengths are measured by performing Raman spectroscopy of the Na-Cs motional states and least-bound molecular state in the two-atom system.
Proceedings ArticleDOI
Ultracold chemistry and dipolar collisions in a quantum gas of polar molecules
Silke Ospelkaus,Amodsen Chotia,Marcio de Miranda,Brian Neyenhuis,Kang-Kuen Ni,Dajun Wang,Jun Ye,Deborah Jin +7 more
TL;DR: In this paper, the authors discuss the control of dipolar collisions and chemical reactions of polar molecules in a regime where quantum statistics, single scattering partial waves, and quantum threshold laws play a dominant role.
Journal ArticleDOI
Building one molecule from a reservoir of two atoms
Lee R. Liu,J. D. Hood,Yichao Yu,Jianhua Zhang,Nicholas R. Hutzler,Till Rosenband,Kang-Kuen Ni +6 more
TL;DR: In this paper, two individual laser-cooled atoms (one sodium and one cesium) are trapped in separate optical tweezers and then merged into one optical dipole trap.
