After a proper definition of the dimerization order parameter for a spins system, I show that this order parameter in the SU (n) (n=2S+ 1 ) antiferromagnetic chains (or equivalently the SU(2) spins chains with Hamiltonians which project out singlet states) is, in the thermodynamic limit, directly proportional to the staggered-magnetization in the corresponding spin-½ XXZ chains which had already been mapped onto the SU (n) chains

Ordering of Energy Levels for Extended SU(N) Hubbard Chain

Tigran Hakobyan

The Lieb-Mattis theorem on the antiferromagnetic ordering of energy levels is generalized to SU (N ) extended Hubbard model with Heisenberg exchange and pair-hopping terms.It is proved that the minimum energy levels among the states from equivalent representations are nondegenerate and ordered according to the dominance order of corresponding Young diagrams.In particular, the ground states form a unique antisymmetric multiplet.The relation with the similar ordering among the spatial wavefunctions with different symmetry classes of ordinary quantum mechanics is discussed also.The Lieb-Mattis theorem on the antiferromagnetic ordering of energy levels is generalized to SU (N ) extended Hubbard model with Heisenberg exchange and pair-hopping terms.It is proved that the minimum energy levels among the states from equivalent representations are nondegenerate and ordered according to the dominance order of corresponding Young diagrams.In particular, the ground states form a unique antisymmetric multiplet.The relation with the similar ordering among the spatial wavefunctions with different symmetry classes of ordinary quantum mechanics is discussed also.

Antiferromagnetic ordering of energy levels for a spin ladder with four-spin cyclic exchange: Generalization of the Lieb-Mattis theorem

Tigran Hakobyan

The Lieb-Mattis theorem is generalized to an antiferromagnetic spin-ladder model with four-spin cyclic exchange interaction. We prove that for $J>2\phantom{\rule{0.3em}{0ex}}\text{K}$ , the antiferromagnetic ordering of energy levels takes place separately in two sectors, which remain symmetric and antisymmetric under the reflection with respect to the longitudinal axis of the ladder. We prove also that at the self-dual point $J=2\phantom{\rule{0.3em}{0ex}}\text{K}$ , the Lieb-Mattis rule holds in the sectors with fixed number of rung singlets. In both cases, it agrees with the similar rule for Haldane chain with appropriate spin number.The Lieb-Mattis theorem is generalized to an antiferromagnetic spin-ladder model with four-spin cyclic exchange interaction.
