A method for solve integrable spin chains combining different representations
Julio Abad, Miguel Rios
A non homogeneous spin chain in the representations and of is analyzed. We find that the naive nested Bethe ansatz is not applicable to this case. A meth…
Diagonal solutions to reflection equations in higher spin XXZ model
Julio Abad, Miguel Rios
A general fusion method to find solutions to the reflection equation in higher spin representations starting from the fundamental one is shown. The method is illustrated by applyin…
Non-diagonal solutions to reflection equations in spin chains
J. Abad, M. Rios
The reflection equations in a spin chain with open boundary conditions are analyzed. We find non diagonal solutions to the boundary matrices. The corresponding hamiltonian…
Integrable Spin Chains Associated to and
J. Abad, M. Rios
The Hoft structure of the central extension of the algebra is considered. The intertwine matrix induces new integrable spin chain…
