Identifying localized and spreading chaos in nonlinear disordered lattices by the Generalized Alignment Index (GALI) method
Bob Senyange, Charalampos Skokos
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 sp…
Chaotic behaviour of disordered nonlinear lattices
Bob Senyange
This thesis focuses on the mechanisms of energy transport in multidimensional heterogeneous lattice models, studying in particular the case of the Klein-Gordon model of coupled anh…
Properties of normal modes in a modified disordered Klein-Gordon lattice: From disorder to order
B. Senyange, J. -J. du Plessis, B. Many Manda +1
We introduce a modified version of the disordered Klein-Gordon lattice model, having two parameters for controlling the disorder strength: , which determines the range of the co…
Chaotic wave packet spreading in two-dimensional disordered nonlinear lattices
Bertin Many Manda, Bob Senyange, Charalampos Skokos
We reveal the generic characteristics of wave packet delocalization in two-dimensional nonlinear disordered lattices by performing extensive numerical simulations in two basic diso…
Characteristics of chaos evolution in one-dimensional disordered nonlinear lattices
B. Senyange, B. Many Manda, Ch. Skokos
We numerically investigate the characteristics of chaos evolution during wave packet spreading in two typical one-dimensional nonlinear disordered lattices: the Klein-Gordon system…
Computational efficiency of symplectic integration schemes: Application to multidimensional disordered Klein-Gordon lattices
B. Senyange, Ch. Skokos
We implement several symplectic integrators, which are based on two part splitting, for studying the chaotic behavior of one- and two-dimensional disordered Klein-Gordon lattices w…
On the symplectic integration of the Klein Gordon lattice model
Bob Senyange
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 mul…
