Entanglement asymmetry in CFT and its relation to non-topological defects

Abstract The entanglement asymmetry is an information based observable that quantifies the degree of symmetry breaking in a region of an extended quantum system. We investigate this measure in the ground state of one dimensional critical systems described by a CFT. Employing the correspondence betwe...
