Modulational instability and discrete breathers in discrete cubic–quintic nonlinear Schrodinger equation
We investigate the properties of modulational instability and discrete breathers in the cubic–quintic discrete nonlinear Schr¨odinger equation. We analyze the regions of modulational instabilities of nonlinear plane waves. Using the Page approach [J.B. Page, Phys. Rev. B 41 (1990) 7835], we derive...
