Deskripsi
The development of higher-order topological insulators enables robust localization of energy at lower-dimensional boundaries. Here the authors demonstrate that partial dislocation in higher order topological insulators can be intuitively understood as a defect-induced topological phase boundary which supports 0D bound states.
