Localized Asymmetric Atomic Matter Waves in Two-Component Bose–Einstein Condensates Coupled with Two-Photon Microwave Field

We investigate localized atomic matter waves in two-component Bose–Einstein condensates coupled by the two-photon microwave field. Interestingly, the oscillations of localized atomic matter waves will gradually decay and finally become non-oscillating behavior even if existing coupling field. In particular, atom numbers occupied in two different hyperfine spin states will appear asymmetric occupations after some time evolution.
