| Abstract: | All posible existed moving nonlinear localized modes for one-dimensional Klein-Gordon diatomic lattice are obtained analytically in the whole ω-q plane of the system by means of the so-called semidiscrete approximation,with which the carrier wave is treated explicitly while the enenlope is described in the continuum approximation.We found both pulse and kink(antikink) envelope moving vibrational modes for this lattice system can be occurred with certain carrier wavenumbers and frequencies in the separated regions of the ω-q plane. |
