Integrable quantum chains combining site states in different representations of
J. Abad, M. Rios
The general expression for the local matrix of a quantum chain with the site space in any representation of is obtained. This is made by generalizing from the…
Integrable Models Associated to Classical Representations of U_q(\widehat{sl(n)})
J. Abad, M. Rios
We describe a representation for , when is not a root of unity, based on the fundamental representation of . As has a Hopf algebra str…
Bethe ansatz equations for quantum chains combining different representations of
J. Abad, M. Rios
The general expression for the local matrix of a quantum chain with the site space in any representation of is obtained. This is made by generalizing from the…
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…
