Scattering of a flat top solitons of cubic - quintic nonlinear Shrodinger equation by delta potential
The flat top soliton is a localized solution of cubic - quintic Nonlinear Shrodinger equation (C-Q NLSE) that can propagate preserving its shape. In this work we consider the interaction of soliton with weak external localized potentials. It is shown that depending on an initial velocity the soli...

| Summary: | The flat top soliton is a localized solution of cubic - quintic Nonlinear Shrodinger
equation (C-Q NLSE) that can propagate preserving its shape. In this work we consider the
interaction of soliton with weak external localized potentials. It is shown that depending on
an initial velocity the soliton may be re
ected or transmitted by potential. The approximate
analytical results based on varational approach qualitatively confirmed by numerical simulations. |
