    "abstract": "We ascertain, following ideas of Arnesen, Bose, and Vedral concerning thermal\nentanglement [Phys. Rev. Lett. {\\bf 87} (2001) 017901] and using the\nstatistical tool called {\\it entropic non-triviality} [Lamberti, Martin,\nPlastino, and Rosso, Physica A {\\bf 334} (2004) 119], that there is a one to\none correspondence between (i) the mixing coefficient $x$ of a Werner state, on\nthe one hand, and (ii) the temperature $T$ of the one-dimensional Heisenberg\ntwo-spin chain with a magnetic field $B$ along the $z-$axis, on the other one.\nThis is true for each value of $B$ below a certain critical value $B_c$. The\npertinent mapping depends on the particular $B-$value one selects within such a\nrange.",
