Intrinsic second-order topological insulators in two-dimensional polymorphic graphyne with sublattice approximation
Abstract In two dimensions, intrinsic second-order topological insulators (SOTIs) are characterized by topological corner states that emerge at the intersections of distinct edges with reversed mass signs, enforced by spatial symmetries. Here, we present a comprehensive investigation within the clas...
