Perturbed Pöschl-Teller oscillators
Within the framework of Lanczos-inspired perturbation theory wave functions and energies in the short-range potential V (x) = a ρ 2 (x) + λ ρ 4 (x) with ρ(x) = sech αx and a small coupling λ are shown obtainable in closed form.
متن کاملInvariant Tori for Periodically Perturbed Oscillators
The response of an oscillator to a small amplitude periodic excitation is discussed. In particular, sufficient conditions are formulated for the perturbed oscillator to have an invariant torus in the phase cylinder. When such an invariant torus exists, some perturbed solutions are in the basin of attraction of this torus and are thus entrained to the dynamical behavior of the perturbed system o...
متن کاملSynchronization of weakly perturbed Markov chain oscillators.
Rate processes are simple and analytically tractable models for many dynamical systems that switch stochastically between a discrete set of quasistationary states; however, they may also approximate continuous processes by coarse-grained, symbolic dynamics. In contrast to limit-cycle oscillators that are weakly perturbed by noise, in such systems, stochasticity may be strong, and topologies mor...
متن کاملPhase reduction method for strongly perturbed limit cycle oscillators.
The phase reduction method for limit cycle oscillators subjected to weak perturbations has significantly contributed to theoretical investigations of rhythmic phenomena. We here propose a generalized phase reduction method that is also applicable to strongly perturbed limit cycle oscillators. The fundamental assumption of our method is that the perturbations can be decomposed into a slowly vary...
متن کاملExplicit symplectic RKN methods for perturbed non-autonomous oscillators: Splitting, extended and exponentially fitting methods
We consider the numerical integration of perturbed non-autonomous oscillatory systems using high order methods. The autonomous case has been efficiently integrated using explicit and symplectic Runge–Kutta–Nyström (RKN) methods like extended RKN methods, exponentially fitting RKN methods and splitting methods for perturbed systems. Recently, it has been shown that explicit and symplectic extend...
