Dark-bright discrete solitons: a numerical study of existence, stability and dynamics
(2011)
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 ...

Quasidiscrete microwave solitons in a split-ring-resonator-based left-handed coplanar waveguide
(2011)
We study the propagation of quasidiscrete microwave solitons in a nonlinear left-handed coplanar waveguide coupled with split-ring resonators. By considering the relevant transmission line analog, we derive a nonlinear ...

Dark-bright gap solitons in coupled-mode one-dimensional saturable waveguide arrays
(2011)
In the present work, we consider the dynamics of dark solitons as one mode of a defocusing photorefractive lattice coupled with bright solitons as a second mode of the lattice. Our investigation is motivated by an experiment ...

Stability of non-time-reversible phonobreathers
(2011)
Non-time reversible phonobreathers are non-linear waves that can transport energy in coupled oscillator chains by means of a phase-torsion mechanism. In this paper, the stability properties of these structures have been ...

Existence of dark solitons in a class of stationary nonlinear Schrödinger equations with periodically modulated nonlinearity and periodic asymptotics
(2011)
In this paper, we give a proof of the existence of stationary dark solitonsolutions or heteroclinic orbits of nonlinear equations of Schrödinger type with periodic inhomogeneous nonlinearity. The result is illustrated with ...

Interaction of moving discrete breathers with interstitial defects
(American Institute of Mathematical Sciences, 2011)
In this paper, interstitial migration generated by scattering with a mobile breather is investigated numerically in a Frenkel-Kontorova onedimensional lattice. Consistent with experimental results it is shown that interstitial ...

Josephson tunnelling of dark solitons in a double-well potential
(2011)
We study the dynamics of matter waves in an effectively one-dimensional Bose-Einstein condensate in a double-well potential. We consider in particular the case when one of the double wells confines excited states. Similar ...

Multibreather and vortex breather stability in Klein–Gordon lattices: equivalence between two different approaches
(2011)
In this work, we revisit the question of stability of multibreather configurations, i.e. discrete breathers with multiple excited sites at the anti-continuum limit of uncoupled oscillators. We present two methods that yield ...
