About properties of IR active lattice vibrations in the vicinity of kinks in the Frenkel-Kontorova model
We present an analysis of an impact of kinks in the FVenkel-Kontorova model on infrared lattice vibrations. Our results show that the vibration of particles involved into the kink formation is very similar to that in a gap mode around a force constant defect. We found that the IR phonon mode intensity possess a universal dependence on certain combination of system parameters and the kinks concentration. On the bases of these results a criterion, which allows to separate the regime of weakly interacting kinks in the system from the regime of kink lattice is proposed. PACS: 63.20.-e
