NON-GROUND-STATE BOSE-EINSTEIN CONDENSATES OF TRAPPED ATOMS

The possibility of creating a Bose condensate of trapped atoms in a no n-ground-state is suggested. Such a nonequilibrium Bose condensate can be formed if one first obtains the conventional Bose condensate in th e ground state and then transfers the condensed atoms to a non-ground- state by means of a resonance pumping. The properties of ground and no n-ground-states are compared and plausible applications of such nonequ ilibrium condensates are discussed. [S1050-2947(97)03912-7].
