Query: Scattering of solitons in binary Bose-Einstein condensates with
  spin-orbit and Rabi couplings   In this paper we study the scattering of solitons in a binary Bose-Einstein
Condensate (BEC) including SO- and Rabi-couplings. To this end, we derive a
reduced ODE model in view to provide a variational description of the
collisional dynamics. Also, we assume negative intra- and inter-component
interaction strengths, such that one obtains localized solutions even in
absence of external potentials. By performing extensive numerical simulations
of this model we observe that, for specific conditions, the final propagation
velocity of the scattered solitons could be highly sensitive to small changes
in the initial conditions, being a possible signature of chaos. Additionally,
there are infinitely many intervals of regularity emerging from the obtained
chaotic-like regions and forming a fractal-like structure of
reflection/transmission windows. Finally, we investigate how the value of the
spin-orbit coupling strength changes the critical velocities, which are
minimum/maximum values for the occurrence of solitons bound-states, as well as
the fractal-like structure.
