中文摘要	We investigate the ground state of spin-orbit-coupled Bose-Einstein condensates confined in concentrically coupled annular traps within the full parameter space accounts for all the nonlinear two-body collisions and the spin-orbit coupling. We find that depending on the ratio between interaction parameters and the strength of spin-orbit coupling, this coupled system presents various ground-state phases. Moreover, phase transition between radial phase separation and azimuthal phase separation can be induced by varying the strength of spin-orbit coupling when the system is first in radial phase separation, while phase transition between phase coexistence and azimuthal phase separation can also be realized through spin-orbit coupling when the system is first in phase coexistence. Finally, the spin texture is studied and the results show that the meron-antimeron pair spontaneously appears as the ground state of this coupled system. We also give an experimental protocol to observe these phenomena in future experiments. DOI: 10.1103/PhysRevA.86.063628
