Query: Low temperature thermodynamics of inverse square spin models in one
  dimension   We present a field-theoretic renormalization group calculation in two loop
order for classical O(N)-models with an inverse square interaction in the
vicinity of their lower critical dimensionality one. The magnetic
susceptibility at low temperatures is shown to diverge like $T^{-a} \exp(b/T)$
with $a=(N-2)/(N-1)$ and $b=2\pi^2/(N-1)$. From a comparison with the exactly
solvable Haldane-Shastry model we find that the same temperature dependence
applies also to ferromagnetic quantum spin chains.
