Discrete nonlinear excitations on an inhomogeneous lattice in a spatially linear potential

AbstractDiscrete nonlinear excitations on an inhomogeneous lattice in a spatially linear potential are investigated. Discrete breathers possessing multiple frequencies are always spatially localized and oscillatory in lime, with oscillatory frequencies depending on an external potential. A number of phenomena associated with the translational symmetry of the system is addressed. The spatially localized, time periodic and quasi-periodic nonlinear coherent excitations comprising multiple-soliton components are presented with exact results for the corresponding energy, momentum and norm. The mean width of a pulse as a measure of localization is also studied.
