m] 
| a phase of matter in which all bosons in a given physical system have been cooled to a temperature near absolute zero and enter the same quantum state. |
Bose-Ein·stein condensate  (bōs'īn'stīn') n. A state of matter that forms below a critical temperature in which all bosons that comprise the matter fall into the same quantum state. Also called superatom. [After Satyendra Nath Bose and Albert Einstein.] |
| su·per·at·om (sōō'pər-āt'əm) n. See Bose-Einstein condensate. |
| Bose-Einstein condensate
A state of matter that forms at low temperatures or high densities in which the wave functions of the bosons that make up the matter overlap. The bosons all fall into the same ground level quantum state. Bose-Einstein condensates were predicted by Einstein in 1925 but not observed experimentally until 1995. Also called superatom. See also state of matter. |
