Scattering of atomic dark-bright solitons from narrow impurities
A. Álvarez, J. Cuevas, F. R. Romero +5
In this work, we study the collision of an atomic dark-bright soliton, in a two-component Bose-Einstein condensate, with a Gaussian barrier or well. First, we present the results o…
Dark-Bright Discrete Solitons: A Numerical Study of Existence, Stability and Dynamics
A. Alvarez, J. Cuevas, F. R. Romero +1
In the present work, we numerically explore the existence and stability properties of different types of configurations of dark-bright solitons, dark-bright soliton pairs and pairs…
Stability of non-time-reversible phonobreathers
J. Cuevas, J. F. R. Archilla, F. R. Romero
Non-time reversible phonobreathers are non-linear waves that can transport energy in coupled oscillator chains by means of a phase-torsion mechanism. In this paper, the stability p…
Discrete moving breather collisions in a Klein-Gordon chain of oscillators
A. Alvarez, F. R. Romero, J. Cuevas +1
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 hav…
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.…
Breather trapping and breather transmission in a DNA model with an interface
A. Alvarez, F. R. Romero, J. F. R. Archilla +2
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 interf…
