Research output: Contribution to journalArticlepeer-review

Abstract

A Klein-Gordon model on a chain or a rectangular lattice endowed with cubic inter-site and on-site forces is presented. It supports a plethora of strictly compact stable discrete breathers which are pinned at all times to their initial support. In the continuum limit radially symmetric uni-nodal and multi-nodal compact breathers emerge.
