Bose-Einstein condensation (BEC) is the occupation of a single quantum state by a large number of identical particles, which implies that the particles are bosons, satisfying Bose-Einstein statistics and allowing for many particles to pile up in the...

Although predicted by physicists Satyendranath Bose (1894-1974) and Albert Einstein (1879-1955) in the early 1920s, the unusual state of matter known as a Bose-Einstein condensate was not created until 1995, when a team led by Eric Cornell and Carl...

As part of the formulation of quantum mechanics in the first third of the 20th century, it was discovered that elementary particles has a quantity besides mass, electric charge, etc. That quantity was given the name spin, since it was somewhat...

A Bose–Einstein condensate (BEC) is a state of matter formed by a system of bosons confined in an external potential and cooled to temperatures very near to absolute zero (0 kelvin or -273.15 °C). Under such supercooled conditions, a large fraction...

Several research groups have reported progress in making and studying Bose-Einstein condensate, a dense cloud of atoms that acts as a lens when chilled. Their work has verified theoretical predictions about the condensates. A dense cloud of sodium atoms chilled to a temperature...

Atoms trapped in the remarkable form of matter known as a Bose-Einstein condensate share one quantum mechanical state, behaving collectively as a single superatom (SN: 7/25/98, p. 54). A new experiment demonstrates how robust, and possibly useful, that coherence can be, even when...

On weekday mornings, the Cristol Chemistry Building at the University of Colorado is a hive of activity. Every hour, hundreds of laptop-toting students file in and out of its theater-style lecture halls, where classes are scheduled back to back.In all, there are 33 courses at...
