Bulk-boundary correspondence and singularity-filling in long-range free-fermion chains
Nick G. Jones, Ryan Thorngren, Ruben Verresen
The bulk-boundary correspondence relates topologically-protected edge modes to bulk topological invariants, and is well-understood for short-range free-fermion chains. Although cas…

Symmetry-resolved entanglement entropy in critical free-fermion chains
Nick G. Jones
The symmetry-resolved Rényi entanglement entropy is the Rényi entanglement entropy of each symmetry sector of a density matrix . This experimentally relevant quantity is known t…
