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…
Regular and chaotic transport of discrete solitons in asymmetric potentials
J. Cuevas, B. Sánchez-Rey, M. Salerno
Ratchet dynamics of topological solitons of the forced and damped discrete double sine-Gordon system are studied. Directed transport occurring both in regular and in chaotic region…
Multibreather and vortex breather stability in Klein--Gordon lattices: Equivalence between two different approaches
J. Cuevas, V. Koukouloyannis, P. G. Kevrekidis +1
In this work, we revisit the question of stability of multibreather configurations, i.e., discrete breathers with multiple excited sites at the anti-continuum limit of uncoupled os…
Josephson tunneling of dark solitons in a double-well potential
H. Susanto, J. Cuevas, P. Kruger
We study the dynamics of matter waves in an effectively one-dimensional Bose-Einstein condensate in a double well potential. We consider in particular the case when one of the doub…
