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。
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.
