The air is so thin at that level that the lonely oxygen atoms can seldom get together and reunite to form normal molecules. When the long darkness of winter creeps over the north polar region ...

Polar diatomic molecules, consisting of potassium and rubidium, have been created with density and temperature close to the regime of quantum degeneracy. The ability to produce ultracold atoms has ...

UC Santa Barbara researchers are working to move cold atom quantum experiments and applications from the laboratory tabletop ...

This is what causes atoms to bond and what holds a molecule together. Electrons can be shared unequally in a molecule, creating a polar molecule. Opposite polar ends of molecules attract and hold one ...
