Nonlinear atomic vibrations and structural phase transitions in strained carbon chains
G. M. Chechin, D. A. Sizintsev, O. A. Usoltsev
We consider longitudinal nonlinear atomic vibrations in uniformly strained carbon chains with the cumulene structure (. With the aid of ab initio simulations, based on…

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…
