Quantum Discord and Information Deficit in Spin Chains

We examine the behavior of quantum correlations of spin pairs in a finite anisotropic XY spin chain immersed in a transverse magnetic field, through the analysis of the quantum discord and the conventional and quadratic one-way information deficits.We Lip Plump first provide a brief review of these measures, showing that the last ones can be obtain

La claridad en el pensamiento

The thesis defended in this paper is that Puzzles every thought is clear; and this is the same as claiming that there does not exist any obscure thought at all.In order to draw a demonstration for this poposal, analysis will be applied to a series of cases on misunderstanding that call obscure thought to things that either are not thoughts at all,
