Single-ion anisotropy effects on the critical behaviors of quantum entanglement and correlation in the spin-1 Heisenberg chain
Wanxing Lin, Yu-Liang Xu, Zhong-Qiang Liu +2
Quantum entanglement and correlations in the spin-1 Heisenberg chain with single-ion anisotropy are investigated using the quantum renormalization group method. Negativity and quan…

Dynamics of entanglement in the one-dimensional anisotropic XXZ model
Han Zhang, Yu-Liang Xu, Rong-Tao Zhang +4
The dynamics of entanglement in the one-dimensional spin-1/2 anisotropic XXZ model is studied using the quantum renormalization-group method. We obtain the analytical expression of…
