Edge modes in Chern-Simons theory on a strip

Erica Bertolini, Michael Doyle, Nicola Maggiore +2

We investigate abelian Chern-Simons gauge theory on a strip geometry with two spatial boundaries. In the presence of boundaries, gauge invariance is broken by boundary conditions,…

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…
