Entanglement and area laws in weakly correlated gaussian states
J. M. Matera, R. Rossignoli, N. Canosa
We examine the evaluation of entanglement measures in weakly correlated gaussian states. It is shown that they can be expressed in terms of the singular values of a particular bloc…

Quantum discord and related measures of quantum correlations in XY chains
N. Canosa, L. Ciliberti, R. Rossignoli
We examine the quantum correlations of spin pairs in the ground state of finite XY chains in a transverse field, by evaluating the quantum discord as well as other related entropic…
