Entanglement in spin-1/2 dimerized Heisenberg systems
Zhe Sun, XiaoGuang Wang, AnZi Hu +1
We study entanglement in dimerized Heisenberg systems. In particular, we give exact results of ground-state pairwise entanglement for the four-qubit model by identifying a Z_2 symm…

Effects of staggered magnetic field on entanglement in the anisotropic XY model
Zhe Sun, XiaoGuang Wang, You-Quan Li
We investigate effects of staggered magnetic field on thermal entanglement in the anisotropic XY model. The analytic results of entanglement for the two-site cases are obtained. Fo…
