RUBIDIUM-85 AND THE LOVE
March 12, 07
“By making a Bose-Einstein condensate in a particular isotope — rubidium-85 — and then changing the magnetic field in which the BEC is sitting, researchers can adjust the wavefunction’s self-interaction between repulsion and attraction. If the self-interaction is repulsive, all the parts of the wavefunction push each other away. If it is attractive, they all pull towards each other, like gravity. Achieving a pure BEC in rubidium-85 required the cloud of atoms to be cooled to about 3 billionths of a degree above absolute zero, the lowest temperature ever achieved.”
See!? Anything is possible if you just have a little science.
