Classical and quantum nonlinear localized excitations in discrete systems
F. R. Romero, J. F. R. Archilla, F. Palmero +4
Discrete breathers, or intrinsic localized modes, are spatially localized, time--periodic, nonlinear excitations that can exist and propagate in systems of coupled dynamical units.…
Effect of the Introduction of Impurities on the Stability Properties of Multibreathers at Low Coupling
J. Cuevas, J. F. R. Archilla, F. R. Romero
sing a theorem dubbed the {\em Multibreather Stabiliy Theorem} [Physica D 180 (2003) 235-255] we have obtained the stability properties of multibreathers in systems of coupled osci…
Interaction of moving discrete breathers with vacancies
J. Cuevas, J. F. R. Archilla, B. Sánchez-Rey +1
In this paper a Frenkel--Kontorova model with a nonlinear interaction potential is used to describe a vacancy defect in a crystal. According to recent numerical results [Cuevas et…
Effect of base-pair inhomogeneities on charge transport along DNA mediated by twist and radial polarons
F. Palmero, J. F. R. Archilla, D. Hennig +1
Some recent results for a three--dimensional, semi--classical, tight--binding model for DNA show that there are two types of polarons, named radial and twist polarons, that can tra…
