Thermodynamic limit and boundary energy of the su(3) spin chain with non-diagonal boundary fields
We investigate the thermodynamic limit of the su(n)-invariant spin chain models with unparallel boundary fields. It is found that the contribution of the inhomogeneous term in the associated T–Q relation to the ground state energy does vanish in the thermodynamic limit. This fact allows us to calcul...
