Description
Quantum Heisenberg antiferromagnets in one dimension withlong-range interactions are studied; a Hamiltonian which has dimerstates composed of nearest-neighbor singlet pairs as eigenstates ofthe system is obtained. We also obtain sufficient conditions underwhich the eigenstates are the ground states. We propose a model whichis very similar to the Haldane-Shastry model but has the dimer groundstates.
