On the dynamics of a seventh-order generalized Hénon-Heiles potential

Autor: Fredy L. Dubeibe, Euaggelos E. Zotos, Wei Chen

Publikováno v: Results in Physics, Vol 18, Iss , Pp 103278- (2020)

This letter deals with the derivation and analysis of a seventh-order generalization of the Hénon-Heiles potential. The new potential has axial and reflection symmetries, and finite escape energy with three channels of escape. Based on SALI indicato

© 2015 American Physical Society. We investigate the scaling behavior of the maximal Lyapunov exponent in chaotic systems with time delay. In the large-delay limit, it is known that one can distinguish between strong and weak chaos depending on the

Chaotic flavor evolution in an interacting neutrino gas

Autor: Steen Hannestad, Rasmus S. L. Hansen

Publikováno v: Hansen, R S & Hannestad, S 2014, ' Chaotic flavor evolution in an interacting neutrino gas ', Physical Review D, vol. 90, 25009 . https://doi.org/10.1103/PhysRevD.90.025009

Neutrino-neutrino refraction can lead to non-periodic flavor oscillations in dense neutrino gases, and it has been hypothesized that some solutions are chaotic in nature. This is of particular interest in the case of neutrino emission from core-colla

Scaling of distributions of sums of positions for chaotic dynamics at band-splitting points

The stationary distributions of sums of positions of trajectories generated by the logistic map have been found to follow a basic renormalization group (RG) structure: a nontrivial fixed-point multi-scale distribution at the period-doubling onset of

We model chaotic diffusion in a symplectic four-dimensional (4D) map by using the result of a theorem that was developed for stochastically perturbed integrable Hamiltonian systems. We explicitly consider a map defined by a free rotator (FR) coupled

Ulam method for the Chirikov standard map

Autor: Dima L. Shepelyansky, Klaus M. Frahm

Publikováno v: The European Physical Journal B: Condensed Matter and Complex Systems
The European Physical Journal B: Condensed Matter and Complex Systems, Springer-Verlag, 2010, 76 (1), pp.57. ⟨10.1140/epjb/e2010-00190-6⟩

We introduce a generalized Ulam method and apply it to symplectic dynamical maps with a divided phase space. Our extensive numerical studies based on the Arnoldi method show that the Ulam approximant of the Perron-Frobenius operator on a chaotic comp

We consider the statistical properties of the gravitational field F in an infinite one-dimensional homogeneous Poisson distribution of particles, using an exponential cut-off of the pair interaction to control and study the divergences which arise. D
