Gap Solitons in Anharmonic Diatomic lattice

Nand Kishore Pandey [3] | Gautam Johri [3] | Anil Kumar Ram [2]


Abstract: we consider a one - dimensional nonlinear diatomic lattice with two different masses (M & gt, m). We find the exact soliton solutions in the forbidden frequency range ( band gap) between the longitudinal acoustic and optical phonon branches by coupled wave method


Keywords: Double Sine Gordon Equations, Critical Points, Gap Solitons, Coupled Wave Method, Saddle Points
