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…

Schwinger boson mean field theory of the Heisenberg Ferrimagnetic Spin Chain
Congjun Wu, Bin Chen, Xi Dai +2
The Schwinger boson mean field theory is applied to the quantum ferrimagnetic Heisenberg chain. There is a ferrimagnetic long range order in the ground state. We observe two branch…

The Effective Theory of Hole Doped Spin-1 Chain
Xi Dai, Bin Chen, Zhao-Bin Su
An effective theory for the hole doped spin-1 antiferromagnetic chain is proposed in this paper. The two branches of low energy quasipaticle excitation is obtained by the diagrammi…
