Effects of alternating interactions and boundary conditions on quantum entanglement of three-leg Heisenberg ladder
Qinghui Li, Lizhen Hu, Panpan Zhang +4
The spin-12 three-leg antiferromagnetic Heisenberg spin ladder is studied under open boundary condition (OBC) and cylinder boundary condition (CBC), using the density matrix renorm…
Phase diagrams, quantum correlations and critical phenomena of antiferromagnetic Heisenberg model on diamond-type hierarchical lattices
Pan-Pan Zhang, Zhong-Yang Gao, Yu-Liang Xu +2
The spin-1/2 antiferromagnetic Heisenberg systems are studied on three typical diamond-type hierarchical lattices (systems A, B and C) with fractal dimensions 1.63, 2 and 2.58, res…
Quantum Quench dynamics in XY spin chain with ferromagnetic and antiferromagnetic interactions
Zhe Wang, Pan-Pan Fang, Yu-Liang Xu +4
In this manuscript we investigate the one-dimensional anisotropic XY model with ferromagnetic and antiferromagnetic interactions, which gives more interesting phase diagrams and dy…
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…
