Effects of edge on-site potential in a honeycomb topological magnon insulator

PA Pantaleón, Y Xian - Journal of the Physical Society of Japan, 2018 - journals.jps.jp
While the deviation of the edge on-site potential from the bulk values in a magnonic
topological honeycomb lattice leads to the formation of edge states in a bearded boundary …
