Scattering theories for the 1D Hubbard model
J. M. P. Carmelo, K. E. Hibberd, N. Andrei
In one-dimensional (1D) non-perturbative many-electron problems such as the 1D Hubbard model the electronic charge and spin degrees of freedom separate into exotic quantum objects.…
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 open supersymmetric U model with boundary impurity
A. Foerster, K. E. Hibberd, J. R. Links +1
An integrable version of the supersymmetric U model with open boundary conditions and an impurity situated at one end of the chain is introduced. The model is solved through the al…
