Competition of Self-Organized Rotating Spiral Autowaves in a Nonequilibrium Dissipative System of Three-Level Phaser

In this report, recent results of numerical investigations of rotating spiral waves (RSW) dynamics in a nonequilibrium dissipative medium of three-level paramagnetic phaser are reviewed and discussed. The main attention was devoted to phenomena caused by increasing/decreasing competition of self-organized RSW, their coexistence with nonspiral dissipative structure (DS), dynamical stabilization/decay of RSW or full collapse of excitations in wide range of quantity of active particles D and control parameters sets {Cm}.
