The ground state of a spin-1 antiferromagnetic BEC with SU(3) SOC for c 0 = 10 , c 2 = 1 , and κ=4.5. (a) The density distribution of each component and the total density distribution of the system. (b) The phase distribution of each component and momentum space distribution. (c) The spin-component distribution and spin texture of the system. The strength of the quartic trap μ=0.1, and the field of view is 6.4 ×6.4 in dimensionless units with ℏ = m = 1 .
