Molecular collisions: From near-cold to ultra-cold

In the past two decades, revolutionary technologies of creating cold and ultracold molecules have provided cutting-edge experiments for studying fundamental phenomena collision physics. To a large degree, recent explosion interest in molecular collisions has been sparked by dramatic progress experimental capabilities theoretical methods, which permit to be explored deep quantum mechanical limit. Tremendous advances field already achieved, authors, from an perspective, provide review these studies exploring nature occurring at temperatures ranging Kelvin nanoKelvin regime, as well applications producing molecules.
