    "abstract": "The qubit entanglement induced by quasiparticle excitations in the Heisenberg\nspin chain and its relationship to the Bethe Ansatz structure of the eigenmodes\nis studied. A phenomenon called entanglement quenching, which suppresses\neigenstate entanglement, is described and shown to be mediated by Goldstone\nmagnons. Scattering states are characterized by short-range entanglement, and\nnever exhibit entanglement at the longest range. In contrast, bound states have\ncomplex long-range entanglement structures.",
