PHASE CHAOS IN THE ANISOTROPIC COMPLEX GINZBURG-LANDAU EQUATION

Of the various interesting solutions found in the two-dimensional comp lex Ginzburg-Landau equation for anisotropic systems, the phase-chaoti c states show particularly novel features. They exist in a broader par ameter range than in the isotropic case, and often even broader than i n one dimension. They typically represent the global attractor of the system. There exist two variants of phase chaos: a quasi-one dimension al and a two-dimensional solution. The transition to defect chaos is o f intermittent type.
