Ultrashort solitons and kinetic effects in nonlinear metamaterials
We present a stability analysis of a modified nonlinear Schr\"odinger equation describing the propagation of ultrashort pulses in negative refractive index media. Moreover, using methods of quantum statistics, we derive a kinetic equation for the pulses, making it possible to analyze and describe partial coherence in metamaterials. It is shown …
