Spin texture of fragile topology
ORAL
Abstract
Topological phases are have been the subject of intense studies over the recent years, as they are interesting both from a fundamental theoretical
perspective and from an experimental perspective. To bring these two directions together, it is crucial to study physical properties that can be linked
to topology. This has been successfully done in many stable topological phases, but similar results are often incomplete or lacking in more recent
theoretical advances of the field. Here, we make some headway towards this idea by presenting a link between fragile topology and momentum-space spin textures. We include a discussion of possible ways to measure this connection.
