In 1978, while I was a postdoctoral fellow at MIT, I read a paper by Art Ashkin (1978) in
which he described how one might slow down an atomic beam of sodium using the radiation …

The authors review progress in understanding the nature of atomic collisions occurring at
temperatures ranging from the millidegrees Kelvin to the nanodegrees Kelvin regime. The …

Photoassociation is the process in which two colliding atoms absorb a photon to form an
excited molecule. The development of laser-cooling techniques for producing gases at …

We have measured the elastic collision cross section for spin polarized atomic cesium.
Neutral cesium atoms are optically cooled, then loaded into a dc magnetic trap. We infer the …

We have observed the spectrum of long range molecular states of singly excited Na 2
formed by photoassociation during ultracold associative ionization collisions of laser-cooled …

As early as 1917, Einstein had predicted that momentum is transferred in the absorption and
emission of light, but it was not until the 1980's that such optical momentum transfer was …

We present an experimental study of the number and density of trapped atoms in a vapor-
cell Zeeman optical trap. We have investigated how the number (and therefore the capture …

We have captured 3.6× 10^ 10 cesium atoms in a magneto-optic trap loaded from a vapor
cell. The 300-fold increase in the number of trapped atoms compared with that of previous …

Theoretical calculations for the ground state and for 83 excited states of the Na2 molecule
are presented in the framework of two independent approaches. The electron–core …

A vector quantum field theory is developed to describe the interaction of an ultracold atomic
ensemble with a laser field. The ultracold atomic ensemble is composed of either bosonic …
