WebMar 1, 2024 · Topological phases of matter are conventionally characterized by the bulk-boundary correspondence in Hermitian systems: The topological invariant of the bulk in dimensions corresponds to the number of -dimensional boundary states. WebFrom the Atiyah-Hierzebruch spectral sequence (AHSS), we identify the subspace that contains the topological information and faithfully derive the AFT bulk-boundary correspondence for both the parent and descendants.

WebIn topological insulators the bulk boundary correspondence is frequently stated as the principle that the number of edge modes equals the difference in Chern numbers at that edge. I found this e.g. in " Topological Band Theory and the Z2 Invariant " by C.L. Kane pp.18 . However in there is no "derivation" to this in the text by C.L. Kane. http://chc.library.umass.edu/state-archives/tag/g/
