Breather initial profiles in chains of weakly coupled anharmonic oscillators

Journal Article (Journal Article)

A systematic correlation between the initial profile of discrete breathers and their frequency is described. The context is that of a very weakly harmonically coupled chain of softly anharmonic oscillators. The results are structurally stable, that is, robust under changes of the on-site potential and are illustrated numerically for several standard choices. A precise genericity theorem for the results is proved. © 2002 Elsevier Science B.V. All rights reserved.
