Multicriticality in the Generalized Schwinger Model
Federico Ambrosino, Bernardo Zan
We consider the generalized Schwinger model. This theory is obtained by coupling the field strength to an auxiliary scalar field and allowing generic potentials . We stud…
Defect flows from functional relations in the asymptotic semiring
Federico Ambrosino, Anatoly Konechny, Ingo Runkel +1
We study perturbations of topological defects by a relevant holomorphic defect field in two-dimensional conformal field theory. This produces translation invariant defects and thes…
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…
Translation invariant defects as an extension of topological symmetries
Federico Ambrosino, Ingo Runkel, Gérard M. T. Watts
The modern way to understand symmetries of a quantum field theory is via its topological defects in various dimensions. In this contribution to the proceedings we focus on line def…
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…
Non-local charges from perturbed defects via SymTFT in 2d CFT
Federico Ambrosino, Ingo Runkel, Gérard M. T. Watts
We investigate non-local conserved charges in perturbed two-dimensional conformal field theories from the point of view of the 3d SymTFT of the unperturbed theory. In the SymTFT we…
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…
Minimal Models RG flows: non-invertible symmetries & non-perturbative description
Federico Ambrosino, Stefano Negro
In this letter we continue the investigation of RG flows between minimal models that are protected by non-invertible symmetries. RG flows leaving unbroken a subcategory of non-inve…
2d QCD and Integrability, Part II: Generalized QCD
Federico Ambrosino, Shota Komatsu
We extend the study of integrable structures and analyticity of the spectrum in large QCD to a broad class of theories called the generalized QCD, which are given by the…
Understanding Fermionic Generalized Symmetries
Federico Ambrosino, Ran Luo, Yi-Nan Wang +1
We explore new aspects of internal fermionic shifting symmetries, present in physical systems such as free Dirac spinors and p-form tensor-spinor fields. We propose a novel procedu…
2d QCD and Integrability, Part I: 't Hooft model
Federico Ambrosino, Shota Komatsu
We study analytic properties and integrable structures of the meson spectrum in large QCD. We show that the integral equation that determines the masses of the mesons, of…
White Dwarf mass-radius relation
Federico Ambrosino
This paper aims to provide an introduction to the problem of determining the mass-radius relationship for white dwarfs. Both Newtonian and general relativistic case are examined, e…
