Ultracold chemistry and its reaction kinetics [PDF]
New Journal of Physics, 2015 We study the reaction kinetics of chemical processes occurring in the ultracold regime and systematically investigate their dynamics. Quantum entanglement is found to play a key role in driving an ultracold reaction towards a dynamical equilibrium.

Magnetic tuning of ultracold barrierless chemical reactions [PDF]
Physical Review Research, 2020 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 fields in achieving such control has remained elusive.

The geometric phase controls ultracold chemistry. [PDF]
Nat Commun, 2015 AbstractThe geometric phase is shown to control the outcome of an ultracold chemical reaction. The control is a direct consequence of the sign change on the interference term between two scattering pathways (direct and looping), which contribute to the reactive collision process in the presence of a conical intersection (point of degeneracy between two

Exotic Chemistry with Ultracold Rydberg Atoms
CHIMIA, 2016 We review recent experiments carried out with dense (1012 cm–3) ultracold (T = 40 ?K) samples of Cs atoms which have the goal to characterize, by high-resolution spectroscopy, the interactions between Cs atoms, Cs+ ions and electrons that lead ...

Cavity-controlled formation of ultracold molecules
New Journal of Physics, 2018 Ultracold ground-state molecules can be formed from ultracold atoms via photoassociation followed by a spontaneous emission process. Typically, the molecular products are distributed over a range of final states. Here, we propose to use an optical cavity

A Globally Accurate Neural Network Potential Energy Surface and Quantum Dynamics Studies on Be+(2S) + H2/D2 → BeH+/BeD+ + H/D Reactions [PDF]
MoleculesChemical reactions between Be+ ions and H2 molecules have significance in the fields of ultracold chemistry and astrophysics, but the corresponding dynamics studies on the ground-state reaction have not been reported because of the lack of a global ...

Bimolecular Chemistry in the Ultracold Regime [PDF]
Annual Review of Physical Chemistry, 2022 Advances in atomic, molecular, and optical physics techniques allowed the cooling of simple molecules down to the ultracold regime ([Formula: see text]1 mK) and opened opportunities to study chemical reactions with unprecedented levels of control. This review covers recent developments in studying bimolecular chemistry at ultralow temperatures.
