Phenomena of the collective behavior of autosolitons in a dissipative structure in InSb

It is shown that the behavior of autosolitons can be considered as the behavior of an ensemble of interacting solitary localized states in the electron-hole plasma. Investigations revealed transitions from the modes of chaotic oscillations of a current in the external circuit of a sample, which are caused by the motion of autosolitons, to regular oscillations, and from regular oscillations to other regular oscillations through bifurcation by doubling the period with increasing the excitation level of the electron-hole plasma. It is concluded that the system which consists of an ensemble of interacting autosolitons possesses the property of self-organization. It is shown that the autosolitons, which travel through the sample in an external longitudinal magnetic field as strong as 13.6×103 A/m, also exhibit synergetic behavior in a dissipative structure in InSb.
