Bulk-edge correspondence
WebJan 23, 2024 · Due to its dependence on the real-space origin and unit cell, however, there is an ambiguity in its use in a bulk-boundary correspondence. Here, we extract an origin-independent part of γ, the so-called intercellular Zak phase γinter, and show that it is a bulk quantity that unambiguously predicts the number of surface modes. WebNov 23, 2011 · This bulk-edge correspondence is rigorously demonstrated for a one-dimensional toy model as well as for graphene ribbons with zigzag edges. The range of k ∥ for which edge states exist in a graphene ribbon is then calculated for arbitrary orientations of the edges. Finally, we show that the introduction of an anisotropy leads to a topological ...
