    "abstract": "It is shown that spontaneous symmetry breaking does not modify the\nground-state entanglement of two spins, as defined by the concurrence, in the\nXXZ- and the transverse field Ising-chain. Correlation function inequalities,\nvalid in any dimensions for these models, are presented outlining the regimes\nwhere entanglement is unaffected by spontaneous symmetry breaking.",
