Moving breathers in a bent DNA model
(2002)
We study the properties of moving breathers in a bent DNA model with short range interaction, due to the stacking of the base pairs, and long range interaction, due to the finite dipole moment of the bonds within each ...

Influence of moving breathers on vacancies migration
(Elsevier, 2003)
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 ...

Interaction of moving discrete breathers with vacancies
(2006)
In this paper a Frenkel–Kontorova model with a nonlinear int eraction potential is used to describe a vacancy defect in a crystal. According t o recent numerical results [Cuevas et al . Phys. Lett. A 315, 364 (2003)] ...

Moving breathers in a DNA model with competing short and long range dispersive interactions
(2002)
Moving breathers is a means of transmitting information in DNA. We study the existence and properties of moving breathers in a DNA model with short range interaction, due to the stacking of the base pairs, and long range ...
