| 摘 要： | 研究准一维简谐势阱中存在自旋轨道耦合（SOC）的自旋-1偶极玻色-爱因斯坦凝聚体，数值求解旋量Gross-Pitaevskii方程，给出磁畴的分布。计算结果表明：磁畴结构与偶极-偶极相互作用（DDIs）密切相关，随着自旋轨道耦合强度和磁化强度的增强，原来的空间对称分布被破坏，随之出现新的分布模式。

| Abstract: | A spin-1 dipolar Bose-Einstein condensate with spin-orbit coupling (SOC) in a quasi-one-dimensional harmonic trap is studied . We focus on ground state domain distribution calculated numerically with spinor Gross-Pitaevskii equation. It was found that the domain structures are greatly affected by dipole-dipole interactions ( DDIs). Spatial symmetry is broken and transition behaviors of distribution pattern are shown as SOC strength and magnetization are increased. |

| Keywords: | domain structure dipolar interaction spin-orbit coupled spinor condensate |
