Fig. 1: Construction of a single edge dislocation.
From: Anomalous and normal dislocation modes in Floquet topological insulators
Volterra cut-and-glue procedure on a square lattice, implemented by removing a line of atoms (open cyan circles), ending at the center or core of the dislocation (orange circle) and subsequently reconnecting (represented by the dashed lines) the sites (red and blue dots) living on the edges (red and blue lines) across it. The corresponding Burgers vector is b = aex.
