Robust multipartite entanglement in dirty topological wires
Multipartite entanglement measured by QFI scaling is robust to finite spatial inhomogeneity in generalized Kitaev chains and corresponds one-to-one with Majorana-hosting phases for nearest-neighbor pairing while showing super-extensive scaling in long-range phases.
