Quantum Discord and Information Deficit in Spin Chains
(Molecular Diversity Preservation International, 2015-03)
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 ...

Rényi entropy and subsystem distances in finite size and thermal states in critical XY chains
(IOP Publishing, 2020-08)
We study the R´enyi entropy and subsystem distances on one interval for the finite size and thermal states in the critical XY chains, focusing on the critical Ising chain and XX chain with zero transverse field. We construct ...
