文摘
- •
Binary mixture of Bose–Einstein condensates with linear interspecies coupling can undergo spontaneous self-stabilization after the strongly chaotic transient regime.
- •
The self-stabilization is accompanied by the onset of spatially separated immiscible solitons.
- •
One of the most important conditions for self-stabilization is the reduction of condensate density due to emittance of ballistically propagating waves.
