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…

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…
