Critical Behaviour of integrable mixed spins chains
S. R. Aladim, M. J. Martins
We construct a mixed spin 1/2 and integrable model and investigate its finite size properties. For a certain conformal invariant mixed spin system the central charge can be dec…

The class of universality of integrable and isotropic GL(N) mixed magnets
S. R. Aladim, M. J. Martins
We discuss a class of transfer matrix built by a particular combination of isomorphic and non-isomorphic GL(N) invariant vertex operators. We construct a conformally invariant magn…
