Quantum Trigonometric Spin Ruijsenaars-Schneider Models from -theoretic Coulomb Branches

Gleb Arutyunov, Lukas Hardi, Rob Klabbers

The paper quantizes the trigonometric spin Ruijsenaars‑Schneider model using the K‑theoretic Coulomb branch of a 4d N=2 necklace quiver gauge theory, constructing an algebra of L‑o…
