Roaming pathways and survival probability in real-time collisional dynamics of cold and controlled bialkali molecules
J. Klos, Q. Guan, H. Li +3
Perfectly controlled molecules are at the forefront of the quest to explore chemical reactivity at ultra low temperatures. Here, we investigate for the first time the formation of…
Quantum spin state selectivity and magnetic tuning of ultracold chemical reactions of triplet alkali-metal dimers with alkali-metal atoms
Rebekah Hermsmeier, Jacek Klos, Svetlana Kotochigova +1
We demonstrate that it is possible to efficiently control ultracold chemical reactions of alkali-metal atoms colliding with open-shell alkali-metal dimers in their metastable tripl…
Effects of Conical Intersections on Hyperfine Quenching of Hydroxyl OH in collision with an ultracold Sr atom
Ming Li, Jacek Klos, Alexander Petrov +2
The effect of conical intersections (CIs) on electronic relaxation, transitions from excited states to ground states, is well studied, but their influence on hyperfine quenching in…
Prospects for laser cooling of polyatomic molecules with increasing complexity
Jacek Kłos, Svetlana Kotochigova
Optical cycling transitions and direct laser cooling have recently been demonstrated for a number of alkaline-earth dimers and trimer molecules. This is made possible by diagonal F…
Magnetic tuning of ultracold barrierless chemical reactions
Timur V. Tscherbul, Jacek Kłos
While attaining external field control of bimolecular chemical reactions has long been a coveted goal of physics and chemistry, the role of hyperfine interactions and dc magnetic f…
Emulating optical cycling centers in polyatomic molecules
Ming Li, Jacek Kłos, Alexander Petrov +1
An optical cycling center (OCC) is a recently coined term to indicate two electronic states within a complex quantum object that can repeatedly experience optical laser excitation…
Final State Resolved Quantum Predissociation Dynamics of SO2(C1B2) and Its Isotopomers via a Crossing with a Singlet Repulsive State
Changjian Xie, Bin Jiang, Jacek Kłos +4
The fragmentation dynamics of predissociative SO2(C1B2) is investigated on an accurate adiabatic potential energy surface (PES) determined from high level ab initio data. This sing…
Notes on ab initio investigation of the CrH molecule and its interaction with He
Jacek Kłos, Michał Hapka, Grzegorz Chałasiński
Potential and dipole moment curves for the CrH(X) molecule were obtained at the internally-contracted multi-reference configuration interaction with single and double excita…
First-principle interaction potentials for metastable He(S) and Ne(P) with closed-shell molecules. Application to Penning-Ionizing systems
Michał Hapka, Grzegorz Chalasinski, Jacek Kłos +1
We present new interaction potential curves, calculated from first-principle, for the HeS)H and HeS)Ar systems, relevant in Penning's ionization experiments…
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…
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…
