摘要：

Tunneling from a chaotic potential well is explained in terms of a set of complex periodic orbits which contain information about the real dynamics inside the well, as well as the complex dynamics under the confining barrier. These orbits are associated with trajectories which are homoclinic to a real trajectory emerging from the optimal tunneling path. The theory is verified by considering a model double-well problem.
