Quantum-group-invariant models: Bethe ansatz and finite-size spectrum
Holger Frahm, Sascha Gehrmann, Rafael I. Nepomechie +1
We consider the quantum integrable spin chain models associated with the Jimbo R-matrix based on the quantum affine algebra , subject to quantum-group-invariant boun…
(Un)solvable Matrix Models for BPS Correlators
Prokopii Anempodistov, Adolfo Holguin, Vladimir Kazakov +1
We propose and study a family of complex matrix models computing the protected two- and three-point correlation functions in SYM. Our description allows us to direc…
A Carroll Limit of AdS/CFT: A Triality with Flat Space Holography?
Andrea Fontanella, Oliver Payne
We construct a novel holographic duality by taking a Carrollian limit of the AdS/CFT correspondence, relating string theory in a Carroll bulk geometry to a Carroll …
An integrable deformed Landau-Lifshitz model with particle production?
Marius de Leeuw, Andrea Fontanella, Juan Miguel Nieto García
We discuss the continuum limit of a non-Hermitian deformation of the Heisenberg XXX spin chain. This model appeared in the classification of solutions of the Yang--Baxte…
Integrability and Conformal Blocks for Surface Defects in SYM
Adolfo Holguin, Hiroki Kawai
We study various aspects of half-BPS surface defect operators in SYM. For defects on generic points on the moduli space we use superconformal symmetry to fix the fo…
QFT on Fuzzy AdS Spaces: Classical Limit and Boundary Correlation Functions
Bojana Brkić, Ilija Burić, Maja Burić +2
Quantum field theory on two- and three-dimensional fuzzy anti-de Sitter spaces is introduced and studied. We find a complete set of solutions to the fuzzy Klein-Gordon equation and…
