Language: | eng | Issue Date: | Jul-2004 | Publisher: | APS | Document Type: | Article | Journal / Series / Working Paper (HSU): | Physical review letters | Volume: | 93 | Issue: | 3 | Publisher Place: | College Park, MD | Abstract: | Dynamical properties of discrete solitons in nonlinear Schrödinger lattices with saturable nonlinearity are studied in the framework of the one-dimensional discrete Vinetskii-Kukhtarev model. Two stationary strongly localized modes, centered on site (A) and between two neighboring sites (B), are obtained. The associated Peierls-Nabarro potential is bounded and has multiple zeros indicating strong implications on the stability and dynamics of the localized modes. Besides a stable propagation of mode A, a stable propagation of mode B is also possible. The enhanced ability of the large power solitons to move across the lattice is pointed out and numerically verified. |
