Quantum Discord and entropic measures of quantum correlations: Optimization and behavior in finite spin chains
N. Canosa, M. Cerezo, N. Gigena +1
We discuss a generalization of the conditional entropy and one-way information deficit in quantum systems, based on general entropic forms. The formalism allows to consider simple…

Factorization and criticality in finite XXZ systems of arbitrary spin
M. Cerezo, R. Rossignoli, N. Canosa +1
We analyze ground state (GS) factorization in general arrays of spins with couplings immersed in nonuniform fields. It is shown that an exceptionally degenerate set of…
