On the calculation of the correlation functions of the ${\mathfrak{sl}}_3$-model by means of the reduced qKZ equation

Hermann Boos, Artur Hutsalyuk, Khazret Nirov

We study the reduced density matrix of the ${\mathfrak{sl}}_3$-invariant fundamental exchange model by means of a novel reduced quantum Knizhnik-Zamolodchikov equation. This gives us…
