Abstract

We Report On The Static And Dynamical Properties Of Multiple Dark-Antidark Solitons (DADs) In Two-Component, Repulsively Interacting Bose-Einstein Condensates. Motivated By Experimental Observations Involving Multiple DADs, We Present A Theoretical Study Which Showcases That Bound States Consisting Of Dark (Antidark) Solitons In The First (Second) Component Of The Mixture Exist For Different Values Of Interspecies Interactions. It Is Found That Ensembles Of Few DADs May Exist As Stable Configurations, While For Larger DAD Arrays, The Relevant Windows Of Stability With Respect To The Interspecies Interaction Strength Become Progressively Narrower. Moreover, The Dynamical Formation Of States Consisting Of Alternating DADs In The Two Components Of The Mixture Is Monitored. A Complex Dynamical Evolution Of These States Is Observed, Leading Either To Sorted DADs Or To Beating Dark-Dark Solitons Depending On The Strength Of The Interspecies Coupling. This Study Demonstrates Clear Avenues For Future Investigations Of DAD Configurations.
