Discrete optic breathers in zigzag chain: analytical study and computer simulation
L. I. Manevitch, A. V. Savin, C. -H. Lamarque
We present analytical and numerical study of discrete breathers identified as localized deformations of valence angles accompanied by change of valence bonds in crystalline polyeth…

Can low-frequency breathers exist in a quasi-1D crystal?
A. V. Savin, E. A. Zubova, L. I. Manevitch
We investigate a quasi-1D crystal: 2D system of coupled linear chains of particles with strong intra-chain and weak inter-chain interactions. Nonlinear dynamics of one of these cha…
