我们提出了一种实验上可行的拓扑界面工程方案，并展示了如何将其用于拓扑非平凡界面的动力学研究以及跨此类界面的缺陷和纹理穿孔。该方法利用原子的内部自旋结构和局部施加的相互作用强度控制来创建具有高度复杂拓扑性质的多粒子态。特别地，我们考虑了自旋玻色-爱因斯坦凝聚体拓扑不同相之间构建的相干界面。
We propose an experimentally feasible scheme for topological interface engineering and show how it can be used for studies of dynamics of topologically nontrivial interfaces and perforation of defects and textures across such interfaces. The method makes use of the internal spin structure of the atoms together with locally applied control of interaction strengths to create many-particle states with highly complex topological properties. In particular, we consider a constructed coherent interface between topologically distinct phases of spinor Bose-Einstein condensates.
