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…
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…
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…
