We report the observation of coexisting Bose-Einstein condensate (BEC) and Fermi gas in a magnetic trap. With a very small fraction of thermal atoms, the (7)Li condensate is quasipure and in thermal contact with a (6)Li Fermi gas. The lowest common temperature is 0.28 muK similar or equal to 0.2(1)T(C) = 0.2(1)T(F) where T(C) is the BEC critical temperature and T(F) the Fermi temperature. The (7)Li condensate has a one-dimensional character.

Abstract
We report the observation of coexisting Bose-Einstein condensate (BEC) and Fermi gas in a magnetic trap. With a very small fraction of thermal atoms, the (7)Li condensate is quasipure and in thermal contact with a (6)Li Fermi gas. The lowest common temperature is 0.28 muK similar or equal to 0.2(1)T(C) = 0.2(1)T(F) where T(C) is the BEC critical temperature and T(F) the Fermi temperature. The (7)Li condensate has a one-dimensional character.File in questo prodotto:
