Feshbach resonances are the essential tool to control the interaction between atoms in
ultracold quantum gases. They have found numerous experimental applications, opening up …

The angular momentum of molecules, or, equivalently, their rotation in three-dimensional
space, is ideally suited for quantum control. Molecular angular momentum is naturally …

This paper presents a review of the current state of the art in the research field of cold and
ultracold molecules. It serves as an introduction to the focus issue ofNew Journal of Physics …

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 …

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

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

Molecular collisions in the quantum regime represent a new opportunity to explore chemical
reactions. Recently, atom-exchangereactions were observed in a trapped ultracold gas of …

The motion of neutral molecules in a beam can be manipulated and controlled with
inhomogeneous electric and magnetic fields. Static fields can be used to deflect or focus …

The last few years have seen rapid progress in the application of laser cooling to molecules.
In this review, we examine what kinds of molecules can be laser cooled, how to design a …

In this study, we achieved magnetic control of reactive scattering in an ultracold mixture of
23Na atoms and 23Na6Li molecules. In most molecular collisions, particles react or are lost …
