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…
Jordan-Wigner fermionization for the one-dimensional Bariev model of three coupled XY chains
X. -W. Guan, A. Foerster, J. Links +1
The Jordan-Wigner fermionization for the one-dimensional Bariev model of three coupled XY chains is formulated. The Lax operator in terms of fermion operators and the quantum R-mat…
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…
Algebraic Bethe Ansatz for Integrable Extended Hubbard Models Arising from Supersymmetric Group Solutions
Anthony J. Bracken, Xiang-Yu Ge, Mark D. Gould +2
Integrable extended Hubbard models arising from symmetric group solutions are examined in the framework of the graded Quantum Inverse Scattering Method. The Bethe ansatz equations…
