Spectral bulk boundary correspondence
Did you know?
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/

By using the SBBC, the odd-frequency Cooper pairs ac-cumulated at the boundary can be evaluated from the physical quantity determined in the bulk over the entire frequency range.
