A basic system of model equations describing the quasi-linear development of the modulational instability in the presence of partial incoherence is derived. This system can be interpreted as balance equations for the number of quasi-particles in the Wigner spectrum where the basic processes which are active are emission and absorption of quasi-particles by quasi-particles with different wave vectors.

Abstract

A basic system of model equations describing the quasi-linear development of the modulational instability in the presence of partial incoherence is derived. This system can be interpreted as balance equations for the number of quasi-particles in the Wigner spectrum where the basic processes which are active are emission and absorption of quasi-particles by quasi-particles with different wave vectors.
