Moving discrete breathers in a $β$-FPU lattice revisited

Autor: Duran, Henry, Cuevas-Maraver, Jesús, Kevrekidis, Panayotis G., Vainchtein, Anna

In the present work we revisit the existence, stability and dynamical properties of moving discrete breathers in $β$-FPU lattices. On the existence side, we propose a numerical procedure, based on a continuation along a sequence of velocities, that

Discrete moving breather collisions in a Klein–Gordon chain of oscillators

Autor: Juan F. R. Archilla, Jesús Cuevas, A. Alvarez, F. R. Romero

We study collision processes of moving breathers with the same frequency, traveling with opposite directions within a Klein-Gordon chain of oscillators. Two types of collisions have been analyzed: symmetric and non-symmetric, head-on collisions. For

Modulating pulse solutions for quasilinear wave equations

Autor: Mark D. Groves, Guido Schneider

Publikováno v: Journal of Differential Equations. 219:221-258

This paper presents an existence proof for symmetric modulating pulse solutions of a quasilinear wave equation. Modulating pulse solutions consist of a pulse-like envelope advancing in the laboratory frame and modulating an underlying wave train; the

Nonsymmetric moving breather collisions in the Peyrard-Bishop DNA model

We study nonsymmetric collisions of moving breathers (MBs) in the Peyrard-Bishop DNA model. In this paper we have considered the following types of nonsymmetric collisions: head-on collisions of two breathers traveling with different velocities; coll

Moving breather collisions in the Peyrard-Bishop DNA model

We consider collisions of moving breathers (MBs) in the Peyrard-Bishop DNA model. Two identical stationary breathers, sep- arated by a fixed number of pair-bases, are perturbed and begin to move approaching to each other with the same module of veloc

Breather trapping and breather transmission in a DNA model with an interface

We study the dynamics of moving discrete breathers in an interfaced piecewise DNA molecule. This is a DNA chain in which all the base pairs are identical and there exists an interface such that the base pairs dipole moments at each side are oriented

Moving breathers in bent DNA with realistic parameters

Publikováno v: idUS. Depósito de Investigación de la Universidad de Sevilla

Recent papers have considered moving breathers (MBs) in DNA models including long range interaction due to the dipole moments of the hydrogen bonds. We have recalculated the value of the charge transfer when hydrogen bonds stretch using quantum chemi

The DNA molecule is modeled by a parabola embedded chain with long-range interactions between twisted base pair dipoles. A mechanism for bubble generation is presented and investigated in two different configurations. Using random normally distribute
