Webas a spectral bulk-boundary correspondence [33]. The odd-frequency pair amplitudes are decomposed into two terms. IfweuseMatsubara-frequencyrepresentation,thefirstterm is proportional to 1/(ωn)which only exists in the presence of ZESABS. On the other hand, the second term is a regular one proportional to ωn which exists even without ZESABS [33]. 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. gophers athletics
