Kinks supersónicos en redes repulsivas
(Real Sociedad Española de Física, 2013-07-07)
We have founds supersonics kinks in a model for the cation layer of mica muscovite. They are proposed as a posible explanation for the dark tracks in the mineral

Static and moving breathers in a DNA model with competing short–range and long–range dispersive interactions
(2001)
So far, all the studies on breathers on DNA have considered models with either short–range or long-range interaction. However, none of them have considered both kinds of interactions. When both interactions are taken ...

Effect of breather existence on reconstructive transformations in mica muscovite
(2008)
Reconstructive transformations of layered silicates as mica muscovite take place at much lower temperatures than expected. A possible explanation is the existence of breathers within the potassium layer. Numerical analysis ...

Kinks in Coulomb’s chains
(Universidad de Sevilla, 2012)
Chains of identical ions, for which the dominant interaction is the electrostatic repulsion, appear in layered silicates. The ions can move almost from site to site. The chains do not explode because the surrounding media ...

Localized oscillations in nonlinear hamiltonian Klein-Gordon lattices. Breathers and Anderson modes
(2002)
There are two different sources of localization in discrete lattices: • Anderson modes in disordered harmonic lattices [1] • Discrete breathers in homogeneous nonlinear lattices [2]

Discrete breathers collisions in nonlinear Schrödinger and Klein-Gordon lattices
(2008)
Collisions between moving localized modes (moving breathers) in non- integrable lattices present a rich outcome. In this paper, some features of the interaction of moving breathers in Discrete Nonlinear Schrödinger and ...

Interaction of moving breathers with an impurity
(World Scientific, 2003)
We analyze the influence of an impurity in the evolution of moving discrete breathers in a Klein–Gordon chain with non-weak nonlinearity. Three different behaviours can be observed when moving breathers interact with the ...

Charge transport in a nonlinear, three-dimensional DNA model with disorder
(WorldScientific, 2003)
We study the transport of charge due to polarons in a model of DNA which takes in account its 3D structure and the coupling of the electron wave function with the H–bond distortions and the twist motions of the base ...

The origin of defects induced in ultra-pure germanium by Electron Beam Deposition
(Springer, 2015)
The creation of point defects in the crystal lattices of various semiconductors by subthreshold events has been reported on by a number of groups. These observations have been made in great detail using sensitive electrical ...
