Phys. Rev. E 69, 016202 (2004) [5 pages]Onset of collective oscillation in chemical turbulence under global feedbackReceived 30 May 2003; published 16 January 2004 Preceding the complete suppression of chemical turbulence by means of global feedback, a different universal type of transition, which is characterized by the emergence of small-amplitude collective oscillation with strong turbulent background, is shown to occur at much weaker feedback intensity. We illustrate this fact numerically in combination with a phenomenological argument based on the complex Ginzburg-Landau equation with global feedback. © 2004 The American Physical Society URL:
