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…

Computational efficiency of numerical integration methods for the tangent dynamics of many-body Hamiltonian systems in one and two spatial dimensions
Carlo Danieli, Bertin Many Manda, Mithun Thudiyangal +1
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 ma…
