Categorical Anomaly Matching
Andrea Antinucci, Christian Copetti, Yuhan Gai +1
Matching 't Hooft anomalies is a powerful tool for constraining the low-energy dynamics of quantum systems and their allowed renormalization group (RG) flows. For non-invertible (o…
't Hooft Anomalies and Defect Conformal Manifolds: Topological Signatures from Modulated Effective Actions
Christian Copetti
Symmetry breaking of continuous symmetries by extended dynamical defects entails the existence of defect families, which form conformal manifolds in a critical setup. In the presen…
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…
