Precision test of statistical dynamics with state-to-state ultracold chemistry
Yu Liu, Ming-Guang Hu, Matthew A. Nichols +4
Chemical reactions represent a class of quantum problems that challenge both the current theoretical understanding and computational capabilities. Reactions that occur at ultralow…
Fluorescence branching ratios and magnetic tuning of the visible spectrum of SrOH
Duc-Trung Nguyen, Timothy C. Steimle, Ivan Kozyryev +2
The magnetic tuning of the low rotational levels in the Xsigma+(0,0,0), Api(0,0,0), and Bsigma+ (0,0,0) electronic states of strontium hydroxide, SrOH, have been experimentally inv…
Cold collisions of polyatomic molecular radicals with S-state atoms in a magnetic field: An ab initio study of He + CH2(X) collisions
T. V. Tscherbul, T. A. Grinev, H. -G. Yu +4
We develop a rigorous quantum mechanical theory for collisions of polyatomic molecular radicals with S-state atoms in the presence of an external magnetic field. The theory is base…
Total angular momentum representation for atom-molecule collisions in electric fields
T. V. Tscherbul
It is shown that the atom-molecule collision problem in the presence of an external electric field can be solved using the total angular momentum representation in the body-fixed c…
Cold heteromolecular dipolar collisions
Brian C. Sawyer, Benjamin K. Stuhl, Mark Yeo +7
We present the first experimental observation of cold collisions between two different species of neutral polar molecules, each prepared in a single internal quantum state. Combini…
Breaking van der Waals molecules with magnetic fields
R. V. Krems
It is demonstrated that weakly bound van der Waals complexes can dissociate in a magnetic field through coupling between the Zeeman levels. The Zeeman predissociation process is sh…
