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…
Integrable generalised spin ladder models based on the SU(1|3) and SU(3|1) algebras
Arlei Prestes Tonel, Angela Foerster, Katrina Hibberd +1
We present two integrable spin ladder models which possess a general free parameter besides the rung coupling J. The models are exactly solvable by means of the Bethe ansatz method…
Quantum spin ladder systems associated with su(2|2)
A. Foerster, K. E. Hibberd, J. R. Links +1
Two integrable quantum spin ladder systems will be introduced associated with the fundamental su(2|2) solution of the Yang-Baxter equation. The first model is a generalized quantum…
