Nonadditive entropy for random quantum spin-S chains

A. Saguia, M. S. Sarandy

We investigate the scaling of Tsallis entropy in disordered quantum spin-S chains. We show that an extensive scaling occurs for specific values of the entropic index. Those values…

Entanglement and local extremes at an infinite-order quantum phase transition

C. C. Rulli, M. S. Sarandy

The characterization of an infinite-order quantum phase transition (QPT) by entanglement measures is analyzed. To this aim, we consider two closely related solvable spin-1/2 chains…

Bell-like inequality for spin-orbit separability of a classical laser beam

C. V. S. Borges, M. Hor-Meyll, J. A. O. Huguenin +1

In analogy with Bell's inequality for two-qubit quantum states we propose an inequality criterion for the non-separability of the spin-orbit degrees of freedom of a classical laser…

Environment-induced entanglement with a single photon

Malena Hor-Meyll, Adriana Auyuanet, Carolina Borges +4

We propose an all-optical setup, which couples different degrees of freedom of a single photon, to investigate entanglement generation by a common environment. The two qubits are r…

Contribution of adiabatic phases to noncyclic evolution

M. T. Thomaz, A. C. Aguiar Pinto, M. Moutinho

We show that the difference of adiabatic phases, that are basis-dependent, in noncyclic evolution of non-degenerate quantum systems have to be taken into account to give the correc…

Classical Correlation and Quantum Discord in Critical Systems

M. S. Sarandy

We discuss the behavior of quantum and classical pairwise correlations in critical systems, with the quantumness of the correlations measured by the quantum discord. We analyticall…

Economical ontological models for discrete quantum systems

Ernesto F. Galvao

I use the recently proposed framework of ontological models [Harrigan et al., arXiv:0709.1149v2] to obtain economical models for results of tomographically complete sets of measure…
