Spatio-temporal dynamics of a deterministic three-level cellular automaton (TLCA) of ZykovMikhailov type (Sov. Phys. – Doklady, 1986, Vol.31, No.1, P.51) is studied numerically. Evolution of spatial structures is investigated both for the original Zykov-Mikhailov model (which is applicable to e. g. Belousov-Zhabotinskii chemical reactions) and for proposed(More)
In the present survey paper, we report some qualitatively new features of emergence, competition and dynamical stabilization of dissipative rotating spiral waves (RSWs) in the cellular-automaton model of laser-like excitable media proposed in arXiv:cond-mat/0410460v2, arXiv:cond-mat/0602345. Part of the observed features are caused by unusual mechanism of(More)
Understanding of the nature of birth, evolution, competition and dynamical stabilization (or destruction) of spatio-temporal dissipative structures (DS) is of great importance to various areas of modern physics, as well as to significant branches of chemistry, biology etc. The phenomenon of self-organization of DS in nonequilibrium systems is nowadays a(More)
Phenomena of emergence of regular and chaotic fine structure (FS) in stimulated emission (SE) power spectra of an autonomous microwave phonon laser (phaser) have been revealed and investigated experimentally in pink ruby at liquid helium temperatures. The phenomenon of a selforganized bottleneck in evolution of the microwave acoustic FS lines has been(More)
The microwave phonon stimulated emission (SE) has been investigated in a solidstate resonator of a non-autonomous acoustic quantum generator (phaser). Branching and long-time refractority (absence of the reaction on the external pulses) for deterministic chaotic and regular processes of SE were observed in the experiments with weak and strong(More)
