One method of doing this has variations using a Zeeman slower and another which uses a pair oforthogonally polarized beams.
One method of doing this has variations using a Zeeman slower and another which uses a pair oforthogonally polarized beams. This process can be achieved by successive rounds of adiabaticmagnetization and demagnetization. One method of doing this uses two rounds of Joule-Thompsonexpansion and is called the Linde cycle. Claude Cohen-Tannoudji developed a method of doing thisusing lasers and the Doppler effect that was used on a sample of rubidium atoms to form the first (*)Bose-Einstein condensate. This process is necessary to create superfluids and superconductors, and a crudeway of doing it is submersion in liquid nitrogen. For 10 points, name this process in which a system losesheat energy and decreases in temperature.
