dc.description.abstractWe suggest a general rule for the shift quantum numbers k of the relative ground states of antiferromagnetic Heisenberg spin rings. This rule generalizes the well-known results of Marshall, Peierls, Lieb, Schultz, and Mattis for even rings. Our rule is confirmed by numerical investigations and rigorous proofs for special cases, including systems with a Haldane gap for N-->infinity. Implications for the total spin quantum number S of relative ground states are discussed as well as generalizations to the XXZ model.
