Spatio-temporal chaos and patterns formation in nonequilibrium media: phenomenological model of electronic turbulence
E. S. Mchedlova, D. I. Trubetskov
Abstract
The processes in nonequilibrium dissipative media caused by coherent structure formation and lead to the complicated dynamics are of interest for nonlinear physics. Here we consider a model of the flow of interacting electronics patterns. Under electronic pattern we understand a small volume of active media, containing electron oscillators. The superradiation phenomenon takes place due to the evolving radiation instability within each small volume of the flow. It is numerically shown that the dynamics of radiation is changed from spatio-temporal complex oscillations to arising of spatial disorder, i. e. chaotic spatial pattern formation.
