我们研究了投射动量空间自旋纹理和Wilson圈缠绕之间的关系，证明了在某些限制对称性设置下，与脆性拓扑相关的带拓扑和自旋拓扑之间的映射.我们的研究结果表明，自旋间隙可以作为一个吸烟枪散装指标脆弱的拓扑结构在特定的情况下。
We study the relationship between projected momentum-space spin textures and Wilson loop winding, proving a map between band topology of and spin topology in certain restricted symmetry settings, relevant to fragile topology. Our results suggest that the spin gap may act as a smoking gun bulk indicator for fragile topology within specific scenarios.
