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…
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…
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 $\…
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…
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…
A Large Twist Limit for Any Operator
Gwenaël Ferrando, Amit Sever, Adar Sharon +1
We argue that for any single-trace operator in SYM theory there is a large twist double-scaling limit in which the Feynman graphs have an iterative structure. Such str…
Mirror channel eigenvectors of the -dimensional fishnets
Sergey Derkachov, Gwenaël Ferrando, Enrico Olivucci
We present a basis of eigenvectors for the graph building operators acting along the mirror channel of planar fishnet Feynman integrals in -dimensions. The eigenvectors of a fis…
QQ-system and Weyl-type transfer matrices in integrable SO(2r) spin chains
Gwenaël Ferrando, Rouven Frassek, Vladimir Kazakov
We propose the full system of Baxter Q-functions (QQ-system) for the integrable spin chains with the symmetry of the Lie algebra. We use this QQ-system to derive new Weyl-typ…
Thermodynamic Bethe Ansatz for Fishnet CFT
Benjamin Basso, Gwenaël Ferrando, Vladimir Kazakov +1
We present the TBA equations and the Y-system for the exact spectrum of general multi-magnon local operators in the -dimensional anisotropic version of the bi-scalar fishnet CFT…
An asymptotic model for the propagation of oceanic internal tides through quasi-geostrophic flow
Gregory L. Wagner, Gwenael Ferrando, William R. Young
Starting from the hydrostatic Boussinesq equations, we derive a time-averaged `hydrostatic wave equation' that describes the propagation of inertia-gravity internal waves through q…
