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

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 …

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

How does a chemical reaction proceed at ultralow temperatures? Can simple quantum
mechanical rules such as quantum statistics, single partial-wave scattering, and quantum …

The goal of the present article is to review the major developments that have led to the
current understanding of molecule–field interactions and experimental methods for …

We report precise measurements of ground-state, Λ-doublet microwave transitions in the
hydroxyl radical molecule (OH). Utilizing slow, cold molecules produced by a Stark …

Atomic physics was revolutionized by the development of forced evaporative cooling, which
led directly to the observation of Bose–Einstein condensation,, quantum-degenerate Fermi …

This article reviews the current state of the art in the field of cold and ultracold molecules and
demonstrates that chemical reactions, inelastic collisions and dissociation of molecules at …

A pulsed beam of ground state OH radicals is slowed down using a Stark decelerator and is
subsequently loaded into an electrostatic trap. Characterization of the molecular beam …

The presence of electric or microwave fields can modify the long-range forces between
ultracold dipolar molecules in such a way as to engineer weakly bound states of molecule …
