Description:
Author(s): L. Ciliberti, N. Canosa, and R. Rossignoli We examine the quantum correlations of spin pairs in the cyclic XX spin-1/2 chain in a transverse field through the analysis of the quantum discord, the geometric discord, and the information deficit. It is shown that while these quantities provide the same qualitative information, being nonzero for... [Phys. Rev. A 88, 012119] Published Mon Jul 22, 2013
