Abstract
Dynamical tunneling is analogous to the more familiar tunneling of regular single particles between two wells, but takes place between two period-one islands in a semi-chaotic classical phase space. We study the dynamical tunneling of a BEC in a modulated anharmonic potential. We find macroscopic nonlinear self-trapping above a critical interaction strength, and derive a dynamical two mode model to explain our results.
