Demystifying integrable QFTs in AdS: No-go theorems for higher-spin charges
António Antunes, Nat Levine, Marco Meineri
Higher-spin conserved currents and charges feature prominently in integrable 2d QFTs in flat space. Motivated by the question of integrable field theories in AdS space, we consider…

1-loop renormalisability of integrable sigma-models from 4d Chern-Simons theory
Sylvain Lacroix, Nat Levine, Anders Wallberg
Large families of integrable 2d sigma-models have been constructed at the classical level, partly motivated by the utility of integrability on the string worldsheet. It is natural…

Bootstrapping bulk locality. Part II: Interacting functionals
Nat Levine, Miguel F. Paulos
Locality of bulk operators in AdS imposes stringent constraints on their description in terms of the boundary CFT. These constraints are encoded as sum rules on the bulk-to-boundar…
