Positive and negative mass solitons in spin-orbit coupled Bose-Einstein condensates
V. Achilleos, D. J. Frantzeskakis, P. G. Kevrekidis +2
We present a unified description of different types of matter-wave solitons that can emerge in quasi one-dimensional spin-orbit coupled (SOC) Bose-Einstein condensates (BECs). This…
Beating dark-dark solitons and Zitterbewegung in spin-orbit coupled Bose-Einstein condensates
V. Achilleos, D. J. Frantzeskakis, P. G. Kevrekidis
We present families of beating dark-dark solitons in spin-orbit (SO) coupled Bose-Einstein condensates. These families consist of solitons residing simultaneously in the two bands…
Matter-wave dark solitons and their excitation spectra in spin-orbit coupled Bose-Einstein condensates
V. Achilleos, J. Stockhofe, P. G. Kevrekidis +2
We present three types of dark solitons in quasi-one-dimensional spin-orbit coupled repulsive Bose-Einstein condensates. Among these families, two are always stable, while the thir…
Matter-wave bright solitons in spin-orbit coupled Bose-Einstein condensates
V. Achilleos, D. J. Frantzeskakis, P. G. Kevrekidis +1
We study matter-wave bright solitons in spin-orbit (SO) coupled Bose-Einstein condensates (BECs) with attractive interatomic interactions. We use a multiscale expansion method to i…
Statics and dynamics of atomic dark-bright solitons in the presence of delta-like impurities
V. Achilleos, P. G. Kevrekidis, V. M. Rothos +1
Adopting a mean-field description for a two-component atomic Bose-Einstein condensate, we study the stat- ics and dynamics of dark-bright solitons in the presence of localized impu…
Stationary states of a nonlinear Schrödinger lattice with a harmonic trap
V. Achilleos, G. Theocharis, P. G. Kevrekidis +3
We study a discrete nonlinear Schrödinger lattice with a parabolic trapping potential. The model, describing, e.g., an array of repulsive Bose-Einstein condensate droplets confined…
