Abstract

We describe a systematic construction of long-range 1D and 2D SU(N) quantum spin models which is based on the algebraic structure of an underlying Wess–Zumino–Witten conformal field theory. The resulting Hamiltonians are put into the context of the Haldane-Shastry model, the paradigmatic example of long-range spin models.

Fußnoten
1
The quantum affine algebra \(\mathcal {U}_q(\widehat{sl}_2)\) of this paper degenerates into the Yangian \(\text {Y}(sl_2)\) as \(q\rightarrow 1\).
 
2
For simplicity we restrict our attention to translation invariant configurations.
