我们将量子区中直接的规则到混沌的隧道机制与改进的半经典区域的共振辅助隧道理论相结合，得到了从规则到混沌相空间区的动态隧穿速率的预测。我们给出了在给定的h区域中识别非线性共振关联性的定性配方。对于具有一个或多个主共振的系统，我们发现与数值非常吻合。
We derive a prediction of dynamical tunneling rates from regular to chaotic phase-space regions combining the direct regular-to-chaotic tunneling mechanism in the quantum regime with an improved resonance-assisted tunneling theory in the semiclassical regime. We give a qualitative recipe for identifying the relevance of nonlinear resonances in a given h regime. For systems with one or multiple dominant resonances we find excellent agreement to numerics.
