Topological Boundary States and the Edge Chain in Semi-Infinite Two-Dimensional Insulators
Ilya Iakoub, Nicolas Levasseur, Richard MacKenzie
We show that it is possible to compute the adiabatically protected edge and corner states of semi-infinite, two-dimensional, topological insulators by considering the first layer o…

Bulk-Boundary Correspondence in Semi-Infinite Chains from Sublattice Zeros
Ilya Iakoub, Nicolas Levasseur, Kylian Lionnet +1
We provide an alternative derivation of the bulk-boundary correspondence for semi-infinite chains. To describe edge states, we analytically continue the usual Bloch Hamiltonian to…
