Twisted traces on abelian quantum Higgs and Coulomb branches
Davide Gaiotto, Justin Hilburn, Jaime Redondo-Yuste +2
We study twisted traces on the quantum Higgs branches of gauge theories, that is, the quantum Hamiltonian reductions of Weyl algebras…
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…
Global Anomalies on the Hilbert Space
Diego Delmastro, Davide Gaiotto, Jaume Gomis
We show that certain global anomalies can be detected in an elementary fashion by analyzing the way the symmetry algebra is realized on the torus Hilbert space of the anomalous the…
Twisted M2 brane holography and sphere correlation functions
Davide Gaiotto, Jacob Abajian
We define and compute algebraically a "perturbative part" of protected sphere correlation functions in the M2 brane SCFTs. These correlation functions are expected to have a hologr…
