Textures of Spin-Orbit Coupled F=2 Spinor Bose Einstein Condensates
We study the textures of F=2 spinor Bose-Einstein condensates (BECs) with
spin-orbit coupling (SOC) induced by a synthetic non-Abelian gauge field. On
the basis of the analysis of the SOC energy and the numerical calculation of
the Gross-Pitaevskii equation, we demonstrate that the textures originate from
the helical modulation of the order parameter (OP) due to the SOC. In
particular, the cyclic OP consists of two-dimensional lattice textures, such as
the hexagonal lattice and the 1/3-vortex lattice, commonly understandable as
the two-dimensional network of the helical modulations.Comment: 5 pages, 5 figure
