On the spectral stability of kinks in 2D Klein-Gordon model with parity-time-symmetric perturbation
Denis I. Borisov, Sergey V. Dmitriev
In a series of recent works by Demirkaya et al. stability analysis for the static kink solutions to the 1D continuous and discrete Klein-Gordon equations with a -symm…
Rate theory of acceleration of the defect annealing driven by discrete breathers
V. I. Dubinko, J. F. R. Archilla, V. Hizhnyakov +1
Novel mechanisms of defect annealing in solids are discussed, which are based on the large amplitude anharmonic lattice vibrations, a.k.a. intrinsic localized modes or discrete bre…
Properties of discrete breathers in graphane from ab initio simulations
G. M. Chechin, S. V. Dmitriev, I. P. Lobzenko +1
A density functional theory (DFT) study of the discrete breathers (DBs) in graphane (fully hydrogenated graphene) was performed. To the best of our knowledge, this is the first dem…
Excitation of high-amplitude localized nonlinear waves as a result of interaction of kink with attractive impurity in sine-Gordon equation
E. G. Ekomasov, A. M. Gumerov, R. R. Murtazin +2
We study properties of the localized solitons to the sine-Gordon equation excited on the attractive impurity by a moving kink. The cases of one- and two-dimensional spatially exten…
