A multi-scale perturbative approach to SU(2)-Higgs classical dynamics: stability of nonlinear plane waves and bounds of the Higgs field mass
V. Achilleos, F. K. Diakonos, D. J. Frantzeskakis +4
We study the classical dynamics of SU(2)-Higgs field theory using multiple scale perturbation theory. In the spontaneously broken phase, assuming small perturbations of the Higgs f…
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…
Multiple dark-bright solitons in atomic Bose-Einstein condensates
D. Yan, J. J. Chang, C. Hamner +6
We present experimental results and a systematic theoretical analysis of dark-br ight soliton interactions and multiple-dark-bright soliton complexes in atomic t wo-component Bose-…
