Free and Interacting Fermionic Conformal Field Theories on the Fuzzy Sphere
Zheng Zhou, Davide Gaiotto, Yin-Chen He
The fuzzy-sphere regularisation is a powerful tool to study conformal field theories (CFT) in three spacetime dimensions. In this paper, we extend its scope to CFTs with local ferm…
Combinatorial proof of a Non-Renormalization Theorem
Paul-Hermann Balduf, Davide Gaiotto
We provide a direct combinatorial proof of a Feynman graph identity which implies a wide generalization of a formality theorem by Kontsevich. For a Feynman graph , we associate…
3D TFTs from 4d BPS Particles
Davide Gaiotto, Heeyeon Kim
We propose a general strategy to build three-dimensional gauge theories with four supercharges which enjoy a supersymmetry enhancement in the IR. The resulting IR SCFTs admit topol…
SYK-Schur duality: Double scaled SYK correlators from supersymmetric gauge theory
Davide Gaiotto, Herman Verlinde
We propose a triality relating the Double-Scaled SYK model, Chern-Simons theory on a disk with an irregular singularity at the center and the outcome of ``real S…
The -function and Defect Changing Operators from Wavefunction Overlap on a Fuzzy Sphere
Zheng Zhou, Davide Gaiotto, Yin-Chen He +1
Defects are common in physical systems with boundaries, impurities or extensive measurements. The interaction between bulk and defect can lead to rich physical phenomena. Defects i…
