Exact Defect Correlation Functions in Chern-Simons Matter Theories
Gwenaël Ferrando, Elior Urisman
We study defect correlators in three-dimensional, large-, conformal field theories with slightly broken higher-spin symmetry. Focusing on the quasi-fermionic theory, we bootstra…
Hypergeometry from -Symmetry: Feynman Integrals in One and Two Dimensions
Gwenaël Ferrando, Florian Loebbert, Amelie Pitters +1
Feynman integrals with generic propagator powers in one and two spacetime dimensions are investigated from various perspectives. In particular, we argue that the class of track int…
Exact Three-Point Functions in Superconformal Field Theories: Integrability vs. Localization
Gwenaël Ferrando, Shota Komatsu, Gabriel Lefundes +1
We propose an integrability approach for planar three-point functions at finite coupling in superconformal field theories obtained as orbifolds of $\…
Correlators of Line Defect and Local Operator in Conformal Field Theories with a Slightly Broken Higher-Spin Symmetry
Gwenaël Ferrando, Amit Sever, Elior Urisman
We study three-dimensional conformal field theories with a large- limit. Leveraging the framework of slightly broken higher-spin symmetry, we bootstrap correlation functions bet…
Bethe ansatz inside Calogero-Sutherland models
Gwenaël Ferrando, Jules Lamers, Fedor Levkovich-Maslyuk +1
We study the trigonometric quantum spin-Calogero-Sutherland model, and the Haldane-Shastry spin chain as a special case, using a Bethe-ansatz analysis. We harness the model's Yangi…
Checkerboard CFT
Mikhail Alfimov, Gwenaël Ferrando, Vladimir Kazakov +1
The Checkerboard conformal field theory is an interesting representative of a large class of non-unitary, logarithmic Fishnet CFTs (FCFT) in arbitrary dimension which have been int…
