Groenewold-Moyal twists, integrable spin-chains and AdS/CFT

Riccardo Borsato, Miguel Garcia Fernandez ยท 2026

We take the first steps to address via integrability the spectral problem of AdS/CFT dual pairs deformed by Groenewold-Moyal twists. In particular, we start by considering a twisted spin-chain that coโ€ฆ
