 abstract = {The ground state and low energy excitations of the SU(m vertical bar n)
supersymmetric Haldane-Shastry spin chain are analyzed. In the
thermodynamic limit, it is found that the ground state degeneracy is
finite only for the SU(m vertical bar 0) and SU(m vertical bar 1) spin
chains, while the dispersion relation for the low energy and low
momentum excitations is linear for all values of in and n. We show that
the low energy excitations of the SU(m vertical bar 1) spin chain are
described by a conformal field theory of m non-interacting Dirac
fermions which have only positive energies; the central charge of this
theory is m/2. Finally, for n >= 1, the partition functions of the SU(m
vertical bar n) Haldane-Shastry spin chain and the SU(m vertical bar n)
Polychronakos spin chain are shown to be related in a simple way in the
thermodynamic limit at low temperatures. (c) 2007 Elsevier B.V. All
