Sažetak
We analyze the XY model characterized by an anisotropy γ in an external magnetic field, h, with respect to its genuine multipartite entanglement content (in the thermodynamic and finite-size case). Despite its simplicity we show that the quantity—detecting genuine multipartite entanglement through permutation operators and being a lower bound on measures—witnesses the presence of genuine multipartite entanglement for nearly all values of γ and h. We further show that the phase transition and scaling properties are fully characterized by this multipartite quantity. Consequently, we provide a useful toolbox for other condensed-matter systems, where bipartite entanglement measures are known to fail.
