Interface Minimal Model Holography and Topological String Theory
Davide Gaiotto, Keyou Zeng
We study the dynamics of 2d fermions coupled to 3d Chern-Simons gauge fields. For gauge group and fermions in the fundamental representation, the resulting interfaces are c…
Categories of Line Defects and Cohomological Hall Algebras
Davide Gaiotto, Nikita Grygoryev, Wei Li
Any four-dimensional Supersymmetric Quantum Field Theory with eight supercharges can be associated to a monoidal category of BPS line defects. Any Coulomb vacuum of such a theory c…
D-branes and the planar limit of Chern-Simons theory I: Link invariants
Davide Gaiotto, Suriyah Rajalingam Kannagi, Sergio Sanjurjo
We revisit the Holographic duality between Chern-Simons theory and the A-model Topological String Theory. We develop a strategy to systematically compute the large s…
The Categorical 't Hooft Expansion
Davide Gaiotto
We review categorical aspects of 't Hooft's large expansion, which is expected to map any Quantum Field Theory of large matrices to a string theory. Our goal is to describe a g…
Categorical 't Hooft expansion and chiral algebras
Davide Gaiotto, Adrián López-Raven, Hanne Silverans +1
Twisted holography captures protected aspects of well-known holographic dualities. We show how the holographic dual B-model background can be systematically derived from the 't Hoo…
Renormalization Group flow in Schur quantization
Federico Ambrosino, Davide Gaiotto
We develop a general formalism to describe the Renormalization Group Flow of Schur indices and fusion algebras of BPS line defects in four-dimensional Supersymmetric Q…
