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…
Escape Dynamics in the Discrete Repulsive ϕ^4-Model
V. Achilleos, A. Álvarez, J. Cuevas +4
We study deterministic escape dynamics in the framework of the discrete Klein-Gordon modelwith a repulsive quartic on-site potential. Using a combination of analytical techniques,…
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…
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…
Free surface instability in a confined suspension jet
Alejandra Alvarez, Eric Clement, Rodrigo Soto
A jet of non-Brownian particles confined in a thin cell and driven by gravitational force is studied both numerically and theoretically. We present a theoretical scheme aimed to de…
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.…
