Entanglement as a topological marker in harmonically confined attractive Fermi–Hubbard chains
We investigate the single-site von Neumann entropy along a harmonically confined superfluid chain, as described by the one-dimensional fermionic Hubbard model with strongly attractive interactions. We find that by increasing the confinement (or equivalently the particle filling), the system undergoe...
