Abstract
Vibrational excitations can exist in non-linear systems which have no counterpart in the corresponding linear systems. In this paper we investigate such excitations in systems where the non-linearity is of an on-site character. In particular, we analyze the existence conditions for localized (and delocalized) excitations, and their interaction with external fields.
