This review is concerned with the physics and chemistry associated with the interactions,
collisions, and reactions of ultracold molecules, that is, molecules having translational …

Collisions of molecules in a thermal gas are difficult to control. Thermal motion randomizes
molecular encounters and diminishes the effects of external radiation or static …

Intestinal colonization by bacteria of oral origin has been correlated with several negative
health outcomes, including inflammatory bowel disease. However, a causal role of oral …

Ultracold molecules offer unprecedented opportunities for the controlled interrogation of
molecular events, including chemical reactivity in the ultimate quantum regime. The …

Advances in atomic, molecular, and optical physics techniques allowed the cooling of simple
molecules down to the ultracold regime (1 mK) and opened opportunities to study chemical …

Measurement of vector correlations in molecular scattering is an indispensable tool for
mapping out interaction potentials. In a coexpanded supersonic beam, we have studied the …

The recent development of a range of new methods for producing samples of gas-phase
molecules that are translationally cold (K) or ultracold (mK) is driving efforts to study reactive …

We report a new experimental method to study reactive ion-molecule collisions at very low
temperatures. A source of laser-cooled ions in a linear Paul trap has been combined with a …

Progress on research in the field of molecules at cold and ultracold temperatures is reported
in this review. It covers extensively the experimental methods to produce, detect and …

Compared to purely atomic collisions, ultracold collisions involving molecules have the
potential to support a much larger number of Fano-Feshbach resonances due to the huge …
