Bulk-boundary correspondence and singularity-filling in long-range free-fermion chains
The bulk-boundary correspondence relates topologically protected edge modes to bulk topological invariants and is well understood for short-range free-fermion chains. Although case studies have considered long-range Hamiltonians whose couplings decay with a power-law exponent α , there has been no...
