Vortex gap solitons in spin-orbit-coupled Bose-Einstein condensates with competing nonlinearities
Xiaoxi Xu, Feiyan Zhao, Yangui Zhou +4
The formation and dynamics of full vortex gap solitons (FVGSs) is investigated in two-component Bose-Einstein condensates with spin-orbit coupling (SOC), Zeeman splitting (ZS), and…
Semidiscrete vortex solitons
Xiaoxi Xu, Guanghao Ou, Zhaopin Chen +4
We demonstrate a possibility of the creation of stable optical solitons combining one continuous and one discrete coordinate, with embedded vorticity, in an array of planar wavegui…
Two-dimensional vortex quantum droplets get thick
Zeda Lin, Xiaoxi Xu, Zikang Chen +3
We study two-dimensional (2D) vortex quantum droplets (QDs) trapped by a thicker transverse confinement with a>1um. Under this circumstance, the Lee-Huang-Yang (LHY) term should be…
Nonlinear modes in spatially confined spin-orbit-coupled Bose-Einstein condensates with repulsive nonlinearity
Xiong-wei Chen, Zhi-gui Deng, Xiao-xi Xu +5
It was found that spatially confined spin-orbit (SO) coupling, which can be induced by illuminating Bose-Einstein condensates (BECs) with a Gaussian laser beam, can help trap a spi…
Semidiscrete quantum droplets and vortices
Xiliang Zhang, Xiaoxi Xu, Yiyin Zheng +5
We consider a binary bosonic condensate with weak mean-field (MF) residual repulsion, loaded in an array of nearly one-dimensional traps coupled by transverse hopping. With the MF…
