Discrete breathers in polyethylene chain
arXiv:cond-mat/0208496 · doi:10.1103/PhysRevB.67.144302
Abstract
The existence of discrete breathers (DBs), or intrinsic localized modes (localized periodic oscillations of transzigzag) is shown. In the localization region periodic contraction-extension of valence C-C bonds occurs which is accompanied by decrease-increase of valence angles. It is shown that the breathers present in thermalized chain and their contribution dependent on temperature has been revealed.
