QKZ-Ruijsenaars correspondence revisited

Nuclear Physics B. 2017. Vol. B922. P. 113-125.
A. Zabrodin, Zotov A.

We discuss the Matsuo-Cherednik type correspondence between the quantum Knizhnik-Zamolodchikov equations associated with GL(N) and the n-particle quantum Ruijsenaars model, with n being not necessarily equal to N. The quasiclassical limit of this construction yields the quantum-classical correspondence between the quantum spin chains and the classical Ruijsenaars models
