A Twist on Scattering from Defect Anomalies
Andrea Antinucci, Christian Copetti, Giovanni Galati +1
In the presence of extended defects, familiar incoming particles can scatter into exotic outgoing states created by twist operators. We show that one possible mechanism driving the…
Confining Strings in a Gapless Phase
Jeremias Aguilera Damia, Giovanni Galati, Giovanni Rizi
We consider the dynamics of confined strings embedded in a gapless four-dimensional theory. To this end, we examine finite-tension string-like solutions to the equations of motion…
Defect Conformal Manifolds from Phantom (Non-Invertible) Symmetries
Andrea Antinucci, Christian Copetti, Giovanni Galati +1
We explore a general mechanism that allows (1+1)d CFTs to have interesting interface conformal manifolds even in the absence of any continuous internal symmetry or supersymmetry. T…
Topological Constraints on Defect Dynamics
Andrea Antinucci, Christian Copetti, Giovanni Galati +1
Extended objects (defects) in Quantum Field Theory exhibit rich, nontrivial dynamics describing a variety of physical phenomena. These systems often involve strong coupling at long…
Holographic duals of symmetry broken phases
Andrea Antinucci, Francesco Benini, Giovanni Rizi
We explore a novel interpretation of Symmetry Topological Field Theories (SymTFTs) as theories of gravity, proposing a holographic duality where the bulk SymTFT (with the gauging o…
Non-Invertible Symmetry in Calabi-Yau Conformal Field Theories
Clay Cordova, Giovanni Rizi
We construct examples of non-invertible global symmetries in two-dimensional superconformal field theories described by sigma models into Calabi-Yau target spaces. Our construction…
Anomalies of non-invertible self-duality symmetries: fractionalization and gauging
Andrea Antinucci, Francesco Benini, Christian Copetti +2
We study anomalies of non-invertible duality symmetries in both 2d and 4d, employing the tool of the Symmetry TFT. In the 2d case we rephrase the known obstruction theory for the T…
Symmetries and topological operators, on average
Andrea Antinucci, Giovanni Galati, Giovanni Rizi +1
We study Ward identities and selection rules for local correlators in disordered theories where a 0-form global symmetry of a QFT is explicitly broken by a random coupling but…
"Zoology" of non-invertible duality defects: the view from class
Andrea Antinucci, Christian Copetti, Giovanni Galati +1
We study generalizations of the non-invertible duality defects present in SU(N) SYM by studying theories with larger duality groups. We focus on 4d $\mathcal{N} =…
The holography of non-invertible self-duality symmetries
Andrea Antinucci, Francesco Benini, Christian Copetti +2
We study how non-invertible self-duality defects arise in theories with a holographic dual. We focus on the paradigmatic example of SYM. The th…
On Continuous 2-Category Symmetries and Yang-Mills Theory
Andrea Antinucci, Giovanni Galati, Giovanni Rizi
We study a 4d gauge theory obtained from a theory by gauging a 0-form symmetry . We show that this theory has a global continuous 2-catego…
Superconformal index of low-rank gauge theories via the Bethe Ansatz
Francesco Benini, Giovanni Rizi
We study the Bethe Ansatz formula for the superconformal index, in the case of 4d super-Yang-Mills with gauge group . We observe that not all solutions to th…
