Do nonlinear waves destroy Anderson localization? Computational and experimental
studies yield subdiffusive nonequilibrium wave packet spreading. Chaotic dynamics and …

We numerically investigate the characteristics of chaos evolution during wave-packet
spreading in two typical one-dimensional nonlinear disordered lattices: the Klein-Gordon …

This book introduces and explores modern developments in the well established field of
Hamiltonian dynamical systems. It focuses on high degree-of-freedom systems and the …

We investigate the computational performance of various numerical methods for the
integration of the equations of motion and the variational equations for some typical classical …

We discuss the effect of heterogeneity on the chaotic properties of the Peyrard-Bishop-
Dauxois nonlinear model of DNA. Results are presented for the maximum Lyapunov …

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 …

Integrable many-body systems are characterized by a complete set of preserved actions.
Close to an integrable limit, a nonintegrable perturbation creates a coupling network in …

The dynamics of electrically neutral or charged particles around a magnetized Kerr–
Newman black hole immersed in an external electromagnetic field can be described by a …

Abstract Implementing the Generalized Alignment Index (GALI) method of chaos detection
we investigate the dynamical behavior of the nonlinear disordered Klein–Gordon lattice …

We reveal the generic characteristics of wave-packet delocalization in two-dimensional
nonlinear disordered lattices by performing extensive numerical simulations in two basic …
