Nonlinear Josephson-type oscillations of a driven, two-component Bose-Einstein condensate

摘要: We propose an experiment that would demonstrate nonlinear Josephson-type oscillations in the relative population of a driven, two-component Bose-Einstein condensate. An initial state is prepared which two condensates exist magnetic trap, each different hyperfine state, where populations and phase between can be controlled within experimental uncertainty. A weak driving field then applied, couples internal states atom consequently transfers atoms back forth condensates. present model this system investigate effect mean on dynamical evolution.
