Since the achievement of quantum degeneracy in gases of chromium atoms in 2004, the
experimental investigation of ultracold gases made of highly magnetic atoms has …

Cooling atoms to ultralow temperatures has produced a wealth of opportunities in
fundamental physics, precision metrology, and quantum science. The more recent …

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

Laser cooling and trapping are central to modern atomic physics. The most used technique
in cold-atom physics is the magneto-optical trap (MOT), which combines laser cooling with a …

We report three-dimensional trapping of an oxide molecule (YO), using a radio-frequency
magneto-optical trap (MOT). The total number of molecules trapped is∼ 1.5× 10 4, with a …

Compared to atoms, molecules possess additional degrees of freedom that can be exploited
in fundamental tests, ultracold chemistry, and engineering new quantum phases in many …

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

We demonstrate one-and two-dimensional transverse laser cooling and magneto-optical
trapping of the polar molecule yttrium (II) oxide (YO). In a 1D magneto-optical trap (MOT), we …

We demonstrate slowing and longitudinal cooling of a supersonic beam of CaF molecules
using counterpropagating laser light resonant with a closed rotational and almost-closed …

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 …
