We investigate the scaling and spatial distribution of genuine multiparticle entanglement in
three-and four-spin reduced states of the one-dimensional XY model at the quantum phase …

We analyze the bipartite and multipartite entanglement for the ground state of the one-
dimensional XY model in a transverse magnetic field in the thermodynamical limit. We …

We evaluate and analyze the exact value of a measure for local genuine tripartite
entanglement in the one-dimensional cluster-Ising model for spin-$\frac {1}{2} $ particles …

We provide insight into the quantum correlations structure present in strongly correlated
systems beyond the standard framework of bipartite entanglement. To this aim we first …

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 …

In this paper, we study quantum phase transitions in both the one-and two-dimensional XXZ
models with either spin S= 1/2 or S= 1 by a local entanglement E v. We show that the …

We study the pairwise entanglement close to separable ground states of a class of one-
dimensional quantum spin models. At T= 0 we find that such ground states separate regions …

We study the multi-spin entanglement for the 1D anisotropic XY model concentrating on the
simplest case of three-spin entanglement. As compared to the pairwise entanglement, three …

We study the effect of symmetry breaking in a quantum phase transition on pairwise
entanglement in spin-1/2 models. We give a set of conditions on correlation functions a …
