Sphere correlation functions and Verma modules
Davide Gaiotto, Tadashi Okazaki
We propose a universal IR formula for the protected three-sphere correlation functions of Higgs and Coulomb branch operators of supersymmetric quantum field theories w…
Aspects of -deformed M-theory
Davide Gaiotto, Jihwan Oh
We explore the properties of -deformed M-theory, with particular focus on the background and coupling to -def…
Condensations in higher categories
Davide Gaiotto, Theo Johnson-Freyd
We present a higher-categorical generalization of the "Karoubi envelope" construction from ordinary category theory, and prove that, like the ordinary Karoubi envelope, our higher…
Mock modularity and a secondary elliptic genus
Davide Gaiotto, Theo Johnson-Freyd
The theory of Topological Modular Forms suggests the existence of deformation invariants for two-dimensional supersymmetric field theories that are more refined than the standard e…
A Note On Some Minimally Supersymmetric Models In Two Dimensions
D. Gaiotto, T. Johnson-Freyd, E. Witten
We explore the dynamics of a simple class of two-dimensional models with supersymmetry, namely sigma-models with target and the minimal possible set of fields. For an…
3d Abelian Gauge Theories at the Boundary
Lorenzo Di Pietro, Davide Gaiotto, Edoardo Lauria +1
A four-dimensional Abelian gauge field can be coupled to a 3d CFT with a symmetry living on a boundary. This coupling gives rise to a continuous family of boundary conformal…
