When the moduli space is an orbifold: Spontaneous breaking of continuous non-invertible symmetries

Jeremias Aguilera Damia, Riccardo Argurio, Soumyadeep Chaudhuri

We investigate theories of Nambu-Goldstone bosons where the spontaneously broken continuous symmetry is non-invertible. In such theories, the vacua generically parameterize an orbi…
