    "abstract": "Equilibrium states of infinite extended lattice systems at high temperature\nare studied with respect to their entanglement. Two notions of separability are\noffered. They coincide for finite systems but differ for infinitely extended\nones. It is shown that for lattice systems with localized interaction for high\nenough temperature there exists no local entanglement. Even more quasifree\nstates at high temperature are also not distillably entangled for all local\nregions of arbitrary size. For continuous systems entanglement survives for all\ntemperatures. In mean field theories it is possible, that local regions are not\nentangled but the entanglement is hidden in the fluctuation algebra.",
