A 315:364-371, 2003 | Subject: | Pattern Formation and Solitons; Adaptation and Self-Organizing Systems; Materials Science | nlin.PS cond-mat.mtrl-sci nlin.AO | 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. | Source: | arXiv, nlin.PS/0306039 | Services: | Forum | Review | PDF | Favorites |
