Abstract

We study the relationship between momentum-space spin textures \textcolor{red}{projected onto the occupied bands} 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, in specific scenarios, the spin gap may act as a smoking gun bulk indicator for fragile topology.
