Influence of moving breathers on vacancies migration
arXiv:nlin/0306039 · doi:10.1016/S0375-9601(03)01097-1
Abstract
A vacancy defect is described by a Frenkel--Kontorova model with a discommensuration. This vacancy can migrate when interacts with a moving breather. We establish that the width of the interaction potential must be larger than a threshold value in order that the vacancy can move forward. This value is related to the existence of a breather centred at the particles adjacent to the vacancy.
