Abstract:

The breaking of the rotation symmetry of spiral waves in two-dimensional complex oscillatory media was discussed. The synchronization defect lines (SDL) accompanied by an intrinsic drift of the pattern were used for the breaking purpose. It was found that when the turbulent character of the medium increases, single vortex motion changes from ballistic flights at a well-defined angle from the SDL. It gives rise to a novel vortex liquid in nonturbulent multispiral regimes.
