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…

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…
