A generalization of the DHR theorem for higher form symmetries
Horacio Casini, Javier M. Magan
The Doplicher-Haag-Roberts (DHR) reconstruction theorem shows that standard (-form) internal symmetries are associated to groups in relativistic quantum field theory in spacetim…
Mutual information from modular flow in CFTs
Cesar A. Agon, Horacio Casini, Umut Gürsoy +1
The operator product expansion (OPE) of twist operators in the replica trick framework enables a long-distance expansion of the mutual information (MI) in conformal field theories…
Selection rules for RG flows of minimal models
Valentin Benedetti, Horacio Casini, Javier M. Magan
Minimal d=2 CFTs are usually classified through modular invariant partition functions. There is a finer classification of ``non complete'' models when S-duality is not imposed. We…
ABJ anomaly as a U(1) symmetry and Noether's theorem
Valentin Benedetti, Horacio Casini, Javier M. Magan
The Adler-Bell-Jackiw anomaly determines the violation of chiral symmetry when massless fermions are coupled to an abelian gauge field. In its seminal paper, Adler noticed that a m…
