In this work we systematically investigate the chaotic energy spreading in prototypical models of disordered nonlinear lattices, the so-called disordered Klein-Gordon (DKG) system, in one (1D) and two (2D) spatial dimensions. The normal modes' expone

Implementing the Generalized Alignment Index (GALI) method of chaos detection we investigate the dynamical behavior of the nonlinear disordered Klein-Gordon lattice chain in one spatial dimension. By performing extensive numerical simulations of sing

We reveal the generic characteristics of wave packet delocalization in two-dimensional nonlinear disordered lattices by performing extensive numerical simulations in two basic disordered models: the Klein-Gordon system and the discrete nonlinear Schr

We investigate the performance of various methods of symplectic integration, which are based on two part splitting of the integration operator, for the numerical integration of multidimensional Hamiltonian systems. We implement these schemes to study
