Query: Outcoupling vector solitons from a Bose-Einstein condensate with
  time-dependent interatomic forces   We discuss the possibility of emitting vector solitons from a two-component
elongated BEC by manipulating in time the inter- or intra-species scattering
lengths with Feshbach resonance tuning. We present different situations which
do not have an analogue in the single species case. In particular, we show
vector soliton out-coupling by tuning the interspecies forces, how the
evolution in one species is controlled by tuning the dynamics of the other, and
how one can implement the so-called supersolitons. The analysis is performed by
numerical simulations of the one-dimensional Gross-Pitaevskii equation. Simple
analytic arguments are also presented in order to give a qualitative insight.
