Viewing Message ``Re: Bose-Einstein condensation in the alkali gases'' by bci1 on 2009-10-05 13:31:41 \section{Bose-Einstein Condensation, or BEC,} can be described as the process occurring only very close to absolute zero (for example, below 1 mK) in which a large fraction of a dilute gas of weakly interacting bosons confined in an external potential have a lowest quantum state (or states) in which their wave functions overlap; hence the name of Bose-Einstein condensate (BEC) attributed to such a system of supercooled weakly interacting bosons with overlapping wave functions. The original theoretical paper was published in 1925 in \emph{Zeitschrift fur Physik} by Satyendra Nath Bose in the German translation of Albert Einstein, and followed in a few theoretical papers by Einstein himself. Recently, there have been several experimental claims --listed in the following references-- reported to have observed BECs in alkali metal gases at very low temperatures. \textbf{References} 1. M.
