Dark-dark solitons and modulational instability in miscible two-component Bose-Einstein condensates
@article{Hoefer2011DarkdarkSA, title={Dark-dark solitons and modulational instability in miscible two-component Bose-Einstein condensates}, author={Mark A. Hoefer and J. J. Chang and Chris Hamner and P. Engels}, journal={Physical Review A}, year={2011}, volume={84}, pages={041605} }
We investigate the dynamics of two miscible superfluids experiencing fast counterflow in a narrow channel. The superfluids are formed by two distinguishable components of a trapped dilute-gas Bose-Einstein condensate (BEC). The onset of counterflow-induced modulational instability throughout the cloud is observed and shown to lead to the proliferation of dark-dark vector solitons. These solitons do not exist in single-component systems, exhibit intriguing beating dynamics, and can experience a…

It is experimentally demonstrated the existence of robust dark-bright-bright (DBB) and dark-dark-bright solitons in a multicomponent F=1 condensate and theoretical analysis shows that small-amplitudesolitons of these types obey universal long-short wave resonant interaction models, namely, Yajima-Oikawa systems.

A system of coupled Gross-Pitaevskii equations with residual nonlinearity that rule the dynamics of the mixture is presented and it is found that the MI can be excited in miscible condensates and altered in immisciblecondensates due to the effect of residual non linearity.

Another critical point for spin superflow is identified, in which transverse magnon excitations are dynamically generated via spin-exchanging collisions, which leads to the transient formation of axial polar spin domains.
