Tunneling rate fluctuations induced by nonlinear resonances: A quantitative treatment based on semiclassical arguments

Description: This article discusses tunneling rate fluctuations induced by nonlinear resonances. The authors investigate the tunneling process between two symmetric stable islands of a forced pendulum Hamiltonian in the weak chaos regime.
