Nonlinear waves in disordered chains: probing the limits of chaos and spreading
J. D. Bodyfelt, T. V. Laptyeva, Ch. Skokos +2
We probe the limits of nonlinear wave spreading in disordered chains which are known to localize linear waves. We particularly extend recent studies on the regimes of strong and we…
SALI: An Efficient Indicator of Chaos with Application to 2 and 3 Degrees of Freedom Hamiltonian Systems
Ch. Antonopoulos, T. Manos, Ch. Skokos
The Smaller Alignment Index (SALI) is a very useful and efficient indicator that can distinguish rapidly and with certainty between ordered and chaotic motion in Hamiltonian system…
Detecting chaos, determining the dimensions of tori and predicting slow diffusion in Fermi--Pasta--Ulam lattices by the Generalized Alignment Index method
Charalampos Skokos, Tassos Bountis, Chris Antonopoulos
The recently introduced GALI method is used for rapidly detecting chaos, determining the dimensionality of regular motion and predicting slow diffusion in multi--dimensional Hamilt…
Detecting Order and Chaos by the Linear Dependence Index (LDI) Method
Chris Antonopoulos, Tassos Bountis
We introduce a new methodology for a fast and reliable discrimination between ordered and chaotic orbits in multidimensional Hamiltonian systems which we call the Linear Dependence…
Stability of Simple Periodic Orbits and Chaos in a Fermi -- Pasta -- Ulam Lattice
Chris Antonopoulos, Tassos Bountis
We investigate the connection between local and global dynamics in the Fermi -- Pasta -- Ulam (FPU) -- model from the point of view of stability of its simplest periodic orbits…
