  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.
