Adrien Arbalestrier, Riccardo Argurio, Giovanni Galati +1
We revisit Maxwell theory in 4d with a boundary, with particular attention to the global properties of the boundary conditions, both in the free (topological) and interacting (conf…

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…
