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…
Exact solvability in contemporary physics
A. Foerster, J. Links, H. -Q. Zhou
We review the theory for exactly solving quantum Hamiltonian systems through the algebraic Bethe ansatz. We also demonstrate how this theory applies to current studies in Bose-Eins…
Integrable Impurity Spin Ladder Systems
Arlei Prestes Tonel, Angela Foerster, Xi-Wen Guan +1
Two integrable spin ladder systems with different types of impurities are proposed. The impurities are introduced in such a way that the integrability of the models is not violated…
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…
Integrable generalised spin ladder models
Angela Foerster, Jon Links, Arlei Prestes Tonel
We present two new integrable spin ladder models which posses three general free parameters besides the rung coupling J. Wang's systems based on the SU(4) and SU(3/1) symmetries ca…
