RG flows, Non-Invertible Symmetries and Matrix Factorisations
Federico Ambrosino, Matthias R. Gaberdiel, Yu Nakayama
We study the behaviour of the topological defect lines of the minimal models that are preserved by the least relevant perturbation to first order. It is u…
Monodromy defects in Chern-Simons theory and Holography
Federico Ambrosino, Jaume Gomis, Suriyah Rajalingam Kannagi
Wilson loop operators in Chern-Simons theory have revealed profound links between quantum field theory, the fractional quantum Hall effect, topology, conformal field theory, and st…
Meromorphic amplitudes from 3-dimensional supersymmetry
Federico Ambrosino, Nathan Haouzi
We establish a new connection between supersymmetric theories and scattering amplitudes. We show that the Coon amplitude coincides with the 3d half-index of the XYZ…
SymTFT in Superspace
Federico Ambrosino, Alessandro Duci, Pietro Antonio Grassi +1
We propose a manifestly supersymmetric formulation of the Symmetry Topological Field Theory (SuSymTFT) for theories with supersymmetry. The SymTFT is a framework that helps organiz…
RG flows of minimal -algebra CFTs via non-invertible symmetries
Federico Ambrosino, Tomáš Procházka
In this letter we study renormalization group (RG) flows between 2d conformal field theories enjoying extended higher-spin -symmetry. We propose a new class of RG flow…
Analytic Langlands correspondence from SoV
Federico Ambrosino, Jörg Teschner
The analytic Langlands correspondence proposed by Etingof, Frenkel and Kazhdan describes the solution to the spectral problems naturally arising in the quantisation of the Hitchin…
