Abstract

We present a mechanism to generate a sequence of shearless curves or attractors to form a band of transport barriers. We consider the labyrinthic nontwist standard map to prepare a scenario with three shearless curves. Dissipation is introduced and three shearless attractors coexist, very close to each other. In both cases a collective transport barrier is formed.
