摘要：

We present a numerical method for obtaining high-accuracy numerical solutions of spatially localized time-periodic excitations on a nonlinear Hamiltonian lattice. We compare these results with analytical considerations of the spatial decay. We show that nonlinear contributions have to be considered, and we obtain very good agreement between the latter and numerical results. We discuss further applications of the method and results. © 1995 The American Physical Society.
