Noise-Enhanced Trapping in Chaotic Scattering
Noise-Enhanced Trapping in Chaotic Scattering
We show that noise enhances the trapping of trajectories in scattering systems. In fully chaotic systems, the decay rate can decrease with increasing noise due to a generic mismatch between the noiseless escape rate and the value predicted by the Liouville measure of the exit set. In Hamiltonian systems with …
