Abstract

In this short report we present some recent results on the thermodynamics of \(\mathrm {su}(m|n)\) supersymmetric spin chains of Haldane–Shastry type, with long-range position-dependent interactions. We first evaluate their partition function, and then show how to express it in terms of supersymmetric Haldane motifs. This key step makes it possible to derive the thermodynamic functions of the system in closed form through a modification of the usual transfer matrix approach. In particular, from the low-temperature behavior of the free energy we obtain a full description of the critical behavior of these chains for low values of m and n.
