Properties of π-mode vibrations in strained carbon chains
G. M. Chechin, D. A. Sizintsev, O. A. Usoltsev
Nonlinear vibrations in strained monoatomic carbon chains are studied with the aid of ab initio methods based on the density functional theory. An unexpected phenomenon of structur…

Nonlinear vibrational modes in graphene: group-theoretical results
G. Chechin, D. Ryabov, S. Shcherbinin
In-plane nonlinear delocalized vibrations in uniformly stretched single-layer graphene (space group P6mm) are considered with the aid of the group-theoretical methods. These method…
