Intermittency and solitons in the driven dissipative nonlinear Schroedinger equation
Journal Article

· Phys. Rev. Lett.; (United States)
The cubic nonlinear Schroedinger equation, in the presence of driving and Landau damping, is studied numerically. As the pump intensity is increased, the system exhibits a transition from intermittency to a two-torus to chaos. The laminar phase of the intermittency is also a two-torus motion which corresponds in physical space to two identical solitons of amplitude determined by a power-balance equation.
