论文摘要
最新的理论和实验研究探索了二元玻色 - 因斯坦冷凝水(BEC)中的磁孤子。在这里,我们证明,当嵌入具有自旋 - 旋转对称性的完整三分量自旋-1歧管中时,这种孤子是SO(3)孤子家族的一部分。为了展示这一点,我们通过实验创建了一种由90度旋转获得的新型域壁磁性孤子(DWM),该旋转由易于轴和易于平面极性相之间的边界组成。 SO(3)孤子之间的碰撞是通过数值求解毛taevskii方程来研究的,这些方程式表现出新的特性,包括旋转和消散孤子自旋极化。
Recent theoretical and experimental research has explored magnetic solitons in binary Bose-Einstein condensates (BECs). Here we demonstrate that such solitons are part of an SO(3) soliton family when embedded within a full three-component spin-1 manifold with spin-rotational symmetry. To showcase this, we have experimentally created a new type of domain wall magnetic soliton (DWMS) obtained by 90 degree rotations, which consist of a boundary between easy-axis and easy-plane polar phases. Collisions between SO(3) solitons are investigated by numerically solving the Gross-Pitaevskii equations, which exhibit novel properties including rotation and dissipation of soliton spin polarization.
