Effect of one-ion L-S coupling on magnetic properties of a correlated spin-orbit system
Zu-Jian Ying, Xi-Wen Guan, Angela Foerster +2
By introducing a basis for a novel realization of the SU(4) Lie algebra, we exactly solve a spin-orbital chain with one-ion - coupling (OILSC) via the Bethe ansatz (BA) appro…

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…
