Abstract

We present evidence that nonlinear resonances govern the tunneling process between symmetry- related islands of regular motion in mixed regular-chaotic systems. In a similar way as for near-integrable tunneling, such resonances induce couplings between regular states within the islands and states that are supported by the chaotic sea. On the basis of this mechanism, we derive a ...
