Thanks for the reply; so I guess I should consider chains with odd number of sites (whether for spin-1/2 or spin-1 chains) to calculate the corresponding topological excitations. Is this correct?
No. You should think Sz_total=1 subspace as 2-spinon excited states. 2-spinon excited states are what experimentally observed (from e.g. neutron). Best regards, -- Ryo IGARASHI, Ph.D. rigarash@hosi.phys.s.u-tokyo.ac.jp OpenPGP fingerprint: BAD9 71E3 28F3 8952 5640 6A53 EC79 A280 6A19 2319
