Antiferromagnetic Heisenberg ladders in a staggered magnetic field
Jize Zhao, Xiaoqun Wang, Tao Xiang +4
We study the low-energy excitations of the spin-1/2 antiferromagnetic Heisenberg chain and -leg (=2, 3, 4) ladders in a staggered magnetic field . We show that ind…

Critical entanglement of XXZ Heisenberg chains with defects
Jize Zhao, Ingo Peschel, Xiaoqun Wang
We study the entanglement properties of anisotropic open spin one-half Heisenberg chains with a modified central bond. The entanglement entropy between the two half-chains is calcu…

Spin Transport Properties in Heisenberg Antiferromagnetic Spin Chains: Spin Current induced by Twisted Boundary Magnetic Fields
Wei Zhuo, Xiaoqun Wang, Yupeng Wang
Spin transport properties of the one-dimensional Heisenberg antiferromagnetic spin systems for both and S=1 are studied by applying twisted boundary magnetic field. The spi…
