![]() ![]() While in one dimension point gap topology invariably leads to the NH skin effect, NH boundary physics is significantly richer in two dimensions. Here, we derive the edge signatures of all two-dimensional phases with intrinsic point gap topology. However, many entries in the resulting periodic table have only been discussed in a formal setting and still lack a physical interpretation in terms of their bulk-boundary correspondence. The classification of point gap topology in all local non-Hermitian (NH) symmetry classes has been recently established.
