Half-vortex soliton lattices in spin-orbit-coupled Bose-Einstein condensates with a quasi-flat band
Chenhui Wang, Yongping Zhang, Vladimir V. Konotop
Periodic potentials with flat bands in their spectra support strongly localized nonlinear excitations. Although a perfectly flat band cannot exist in a continuous system, a spin-or…

Transfer of solitons and half-vortex solitons via adiabatic passage
Chenhui Wang, Yongping Zhang, V. V. Konotop
We show that transfer of matter-wave solitons and half-vortex solitons in a spin-orbit coupled Bose-Einstein condensate between two (or more) arbitrarily chosen sites of an optical…

Stabilizing period-doubled density waves by spin-orbit coupling in Bose-Einstein condensates in optical lattices
Chenhui Wang, Yongping Zhang
In atomic Bose-Einstein condensates in optical lattices, mean-field energy can support the existence of period-doubled density waves, which are similar to Bloch waves but have the…
