Collective coordinates and length-scale competition in spatially inhomogeneous soliton-bearing equations

A Sánchez, AR Bishop - SIAM review, 1998 - SIAM
Perturbed, one-dimensional, integrable (ie, soliton-bearing) equations arise in many applied
contexts when trying to improve the (usually highly idealized) description of problems of …

Discrete breathers in dissipative lattices

JL Marín, F Falo, PJ Martínez, LM Floría - Physical Review E, 2001 - APS
We study the properties of discrete breathers, also known as intrinsic localized modes, in the
one-dimensional Frenkel-Kontorova lattice of oscillators subject to damping and external …

Moving breathers in a DNA model with competing short-and long-range dispersive interactions

J Cuevas, JFR Archilla, YB Gaididei… - Physica D: Nonlinear …, 2002 - Elsevier
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 …

Demonstration of the stability or instability of multibreathers at low coupling

JFR Archilla, J Cuevas, B Sánchez-Rey… - Physica D: Nonlinear …, 2003 - Elsevier
Whereas there exists a mathematical proof for one-site breathers stability, and an
unpublished one for two-site breathers, the methods for determining the stability properties …

Influence of moving breathers on vacancies migration

J Cuevas, C Katerji, JFR Archilla, JC Eilbeck… - Physics Letters A, 2003 - Elsevier
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 …

Bright and dark breathers in Fermi-Pasta-Ulam lattices

B Sánchez-Rey, G James, J Cuevas… - Physical Review B …, 2004 - APS
In this paper we study the existence and linear stability of bright and dark breathers in one-
dimensional FPU lattices. On the one hand, we test the range of validity of a recent breathers …

Discrete breathers and Anderson modes: two faces of the same phenomenon?

JFR Archilla, RS MacKay, JL Marin - Physica D: Nonlinear Phenomena, 1999 - Elsevier
Time-periodic localized oscillations occur in a variety of contexts, in particular in weakly
coupled anharmonic lattices and in disordered harmonic networks of oscillators, where they …

Moving breathers in a bent DNA model

J Cuevas, F Palmero, JFR Archilla, FR Romero - Physics Letters A, 2002 - Elsevier
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 …

Dark breathers in Klein-Gordon lattices. Band analysis of their stability properties

A Alvarez, JFR Archilla, J Cuevas… - New Journal of …, 2002 - iopscience.iop.org
Discrete bright breathers are well known phenomena. They are localized excitations that
consist of a few excited oscillators in a lattice and the rest of them having very small …

Stationary and moving breathers in a simplified model of curved alpha--helix proteins

JFR Archilla, YB Gaididei… - Journal of Physics A …, 2002 - iopscience.iop.org
We study the existence, stability and movability of breathers in a model for alpha–helix
proteins. This model basically consists of a chain of dipole moments parallel to it. The …
