New static structures in the strained carbon and boron chains
George Chechin, Victoria Lapina
We discuss bi-structures with one or two long bonds in the central part of the strained monoatomic chains appearing abruptly as a result of hard bifurcations of the static form wit…

Static structures of strained carbon chains:DFT-modeling vs classical modeling of the chain with Lennard-Jones potential
George Chechin, Victoria Lapina
We proved earlier that in the strained monoatomic chains with Lennard-Jones potential there can exist an equilibrium static bi-structure, which corresponds to N - 1 equal short int…

Discrete breathers of new type in monoatomic chains
G. M. Chechin, V. S. Lapina
In strained monoatomic chains with Lennard-Jones interactions, we revealed a stable static non-homogeneous structure appearing as a result of a certain phase transition. Positions…
