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…
Wannier solitons in spin-orbit-coupled Bose-Einstein condensates in optical lattices with a flat-band
Chenhui Wang, Yongping Zhang, V. V. Konotop
We investigate families of soliton solutions in a spin-orbit coupled Bose-Einstein condensate embedded in an optical lattice, which bifurcate from the nearly flat lowest band. Unli…
Instabilities of a Bose-Einstein condensate with mixed nonlinear and linear lattices
Jun Hong, Chenhui Wang, Yongping Zhang
Bose-Einstein condensates (BECs) in periodic potentials generate interesting physics on the instabilities of Bloch states. The lowest-energy Bloch states of BECs in pure nonlinear…
Spin-orbit-coupled spin-1 Bose-Einstein condensates in a toroidal trap: even-petal-number necklacelike state and persistent flow
Keyan Liu, Huaxin He, Chenhui Wang +2
Spin-orbit coupling has novel spin-flip symmetries, a spin-1 spinor Bose-Einstein condensate owns meaningful interactions, and a toroidal trap is topologically nontrivial. We incor…
