Transition to antispirals in the complex Ginzburg-Landau equation

We report a continuous transition from outwardly rotating spiral waves to antispirals in the complex Ginzburg- Landau equation. Numerical simulations demonstrate that the normal spiral to antispiral transition is fulfilled through a rest spiral wave with zero propagation speed. The propagation direction of spiral waves and the power law behaviour close to the transition boundary are examined.Physics, MultidisciplinarySCI(E)中国科学引文数据库(CSCD)0ARTICLE81437-14402
