Final state sensitivity in noisy chaotic scattering
Alexandre R. Nieto, Jesús M. Seoane, Miguel A. F. Sanjuán
The unpredictability in chaotic scattering problems is a fundamental topic in physics that has been studied either in purely conservative systems or in the presence of weak perturb…
Trapping enhanced by noise in nonhyperbolic and hyperbolic chaotic scattering
Alexandre R. Nieto, Jesús M. Seoane, Miguel A. F. Sanjuán
The noise-enhanced trapping is a surprising phenomenon that has already been studied in chaotic scattering problems where the noise affects the physical variables but not the param…
Measuring the transition between nonhyperbolic and hyperbolic regimes in open Hamiltonian systems
Alexandre R. Nieto, Euaggelos E. Zotos, Jesús M. Seoane +1
We show that the presence of KAM islands in nonhyperbolic chaotic scattering has deep implications on the unpredictability of open Hamiltonian systems. When the energy of the syste…
Resonant behavior and unpredictability in forced chaotic scattering
Alexandre R. Nieto, Jesús M. Seoane, J. E. Alvarellos +1
Chaotic scattering in open Hamiltonian systems is a topic of fundamental interest in physics, which has been mainly studied in the purely conservative case. However, the effect of…
