Konstantinidis, LeonidasConstantoudis, VassiliosΝικολαΐδης, Κλεάνθης A.SingaporeWe consider the problem of a classical Morse oscillator driven by an external periodic field of controllable characteristics and study systematically the effects of the initial phase of the external field on the probability of escape upon molecular dissociation at the end of the interaction time. First, it is shown that such effects indeed exist and may become important depending on the field amplitude and frequency. Then, an explanation is given in terms of the energy exchanges between the basic periodic orbits and the external field and of the associated modifications of the shape of regular islands in phase space. Finally, we exploit this explanation in order to make predictions regarding the behavior of the escape probability as a function of the initial phase and frequency of the external field.2587-25960218-1274https://hdl.handle.net/10442/1280210.1142/S0218127411029951engWorld Scientific Publ Company Pte Limited© WORLD SCIENTIFIC PUBL CO PTE LTD© WORLD SCIENTIFIC PUBL CO PTE LTDInternational Journal of Bifurcation and ChaosKAM toriMathematics, Interdisciplinary ApplicationsHamiltonian systemMultidisciplinary SciencesMorse oscillatorCLASSICAL DYNAMICS OF ESCAPE IN A PERIODICALLY DRIVEN UNBOUND HAMILTONIAN SYSTEM: INITIAL PHASE EFFECTSΆρθρο σε επιστημονικό περιοδικό2011-09Δημοσίευση σε περιοδικόPublication in journalΤεχνολογία μέσωνMedia TechnologyΜαθηματικάMathematicsFrascati 42Επιστημονικό άρθροScientific articleΕθνικό Ίδρυμα Ερευνών (ΕΙΕ)Greek Aggregator OpenArchives.gr | National Documentation Centre (EKT)
