WebYou thus obtain a 2-dimensional system, which is infinite along y, but finite along x, with a left edge and a right edge. From 2A), you find that in the bulk gap, there is 1 edge state on the right edge moving up (more precisely, one more moving up than moving down) From 2B), you find an edge state on the left edge, moving down. mmd カメラ補間曲線登録
