All-optical spin-selective control and shaping of frequency conversion pathways
Xiaoxi Xu, Mai Tal, Danielle Ben-Haim +1
The interplay between optical spin and crystal symmetry provides a powerful mechanism to control light-matter interaction, enabling advances in imaging, holography, sensing, signal…
Reconfigurable Geometric Phase Matching by Multilayered Nonlinear Thin-Film Crystals
Danielle Ben-Haim, Mai Tal, Xiaoxi Xu +1
Phase matching is essential for efficient energy transfer in nonlinear wave-mixing processes. Traditional methods, such as birefringent and quasi-phase matching, have remained conc…
Semidiscrete optical vortex droplets in quasi-phase-matched photonic crystals
Xiaoxi Xu, Feiyan Zhao, Jiayao Huang +6
A new scheme for producing semidiscrete self-trapped vortices (\textquotedblleft swirling photon droplets\textquotedblright ) in photonic crystals with competing quadratic ($χ^{(2)…
Vortex solitons in quasi-phase-matched photonic crystals
Feiyan Zhao, Xiaoxi Xu, Hexiang He +5
We report solutions for stable compound solitons in a three-dimensional quasi-phase-matched photonic crystal with the quadratic () nonlinearity. The photonic crystal is in…
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…
