Elliptic spin Ruijsenaars-Schneider integrable models from 5d 𝒩=1 gauge theories

Abstract

We show that the Coulomb branches of 5d 𝒩=1 necklace quiver gauge theories on ℝ3 × T2 are identified with the phase spaces of elliptic spin Ruijsenaars-Schneider models with dynamical inhomogeneities. This identification resolves the long-standing problem of determining a Poisson structure and a quantization of these models. We further show that the resulting quantum system is the integrable system governing supersymmetric indices of 4d 𝒩=1 theories of class 𝒮k.
