dc.description.abstract | the present work, we numerically explore the existence and stability properties
of different types of configurations of dark-bright solitons, dark-bright soliton pairs
and pairs of dark-bright and dark solitons in discrete settings, starting from the
anti-continuum limit. We find that while single discrete dark-bright solitons have
similar stability properties to discrete dark solitons, their pairs may only be stable
if the bright components are in phase and are always unstable if the bright components
are out of phase. Pairs of dark-bright solitons with dark ones have similar
stability properties as individual dark or dark-bright ones. Lastly, we consider collisions
between dark-bright solitons and between a dark-bright one and a dark one.
Especially in the latter and in the regime where the underlying lattice structure
matters, we find a wide range of potential dynamical outcomes depending on the
initial soliton speed. | es |
