Design of fragile topological flat bands in an optical microcavity array
Topological flat bands are increasingly recognized as an important paradigm to study the effects of quantum geometry and topology in strongly correlated systems. The recently discovered theory of fragile topology offers an alternative approach toward the understanding and realization of topological phases of matter. In Bosonic systems, though fragile topological …
