Dynamics of wave packets in the frame of third-order nonlinear Schrödinger equation

Dynamics of wave packets described by the third-order nonlinear Schrödinger equation is considered employing numerical methods. It is shown that initial pulse tends to one or a few solitons plus a linear quasi-periodic wave under the condition of the same signs of parameters of the third-order linea...

Description
Summary:Dynamics of wave packets described by the third-order nonlinear Schrödinger equation is considered employing numerical methods. It is shown that initial pulse tends to one or a few solitons plus a linear quasi-periodic wave under the condition of the same signs of parameters of the third-order linear dispersion and nonlinear dispersion. The number and parameters of the solitons depend on the magnitudes of both initial pulse parameters and parameters of the equation.
