We find a new type of optical vector soliton that originates from trapping of a dipole mode by the soliton-induced waveguides. These solitons, which appear as a consequence of the vector nature ofâ€¦ (More)

We obtain the most general matrix criterion for stability and instability of multicomponent solitary waves by considering a system of N incoherently coupled nonlinear Schrodinger equations. Solitonâ€¦ (More)

We reveal the origin of the persistent oscillations of solitary waves in a quadratically nonlinear medium. It is found that the oscillations are closely correlated to a nontrivial discrete eigenmodeâ€¦ (More)

A Frenkel-Kontorova type of model is proposed to describe the dynamics of excess atoms (kinks) or vacancies (anti-kinks) in two parallel chains of atoms adsorbed on a crystal surface. Various dynamicâ€¦ (More)
