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…
Symmetry-breaking Effects for Polariton Condensates in Double-Well Potentials
A. S. Rodrigues, P. G. Kevrekidis, J. Cuevas +2
We study the existence, stability, and dynamics of symmetric and anti-symmetric states of quasi-one-dimensional polariton condensates in double-well potentials, in the presence of…
Multibreathers in Klein-Gordon chains with interactions beyond nearest neighbors
V. Koukouloyannis, P. G. Kevrekidis, J. Cuevas +1
We study the existence and stability of multibreathers in Klein-Gordon chains with interactions that are not restricted to nearest neighbors. We provide a general framework where s…
Beating dark-dark solitons in Bose-Einstein condensates
D. Yan, J. J. Chang, C. Hamner +6
Motivated by recent experimental results, we study beating dark-dark solitons as a prototypical coherent structure that emerges in two-component Bose-Einstein condensates. We showc…
Dark lattice solitons in one-dimensional waveguide arrays with defocusing saturable nonlinearities and alternating couplings
Andrey Kanshu, Christian E. Rüter, Detlef Kip +2
In the present work, we examine "binary" waveguide arrays, where the coupling between adjacent sites alternates between two distinct values and and a saturable nonlinea…
