Ground-state and thermal entanglements in a non-Hermitian XY system with real and imaginary magnetic fields
Yue Li, Pan-Pan Zhang, Li-Zhen Hu +2
In this manuscript, we study the non-Hermitian spin-1/2 XY model in the presence of the alternating, imaginary and transverse magnetic fields. For the two-site spin system, we solv…
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…
Thermal entanglement between non-nearest-neighbor spins on fractal lattices
Yu-Liang Xu, Lu-Shun Wang, Xiang-Mu Kong
We investigate thermal entanglement between two non-nearest-neighbor sites in ferromagnetic Heisenberg chain and on fractal lattices by means of the decimation renormalization-grou…
Long-time tails in the random transverse Ising chain
Zhong-Qiang Liu, Xiang-Mu Kong, Su-Rong Jiang +1
Taking one-dimensional random transverse Ising model (RTIM) with the double-Gaussian disorder for example, we investigated the spin autocorrelation function (SAF) and associated sp…
