Universality of Magic in Local Quantum Field Theory
Valentin Benedetti, Atish Dabholkar, Marcello Dalmonte
We show that no stabilizer state in a discrete realization of a local quantum field theory can flow in the continuum to the vacuum or to any state that resembles the vacuum at shor…
Jones index from Rényi entropies in the Ising conformal field theory
Valentin Benedetti, Isai Davila-Cuba, Erik Tonni
We study the relation between the Jones index and the Rényi entropies of two disjoint intervals on the line and of the ground state for a generic value of the Rényi index in the tw…
Non-invertible symmetries and selection rules for RG flows of coset models
Valentin Benedetti, Paul Fendley, Javier M. Magan
We analyze superselection sectors, non-invertible symmetries and selection rules for RG flows triggered via perturbations of a UV two-dimensional conformal field theory (CFT).…
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…
Modular invariance as completeness
Valentin Benedetti, Horacio Casini, Yasuyuki Kawahigashi +2
We review the physical meaning of modular invariance for unitary conformal quantum field theories in d=2. For QFT models, while T invariance is necessary for locality, S invariance…
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…
Entanglement entropy of a Rarita-Schwinger field in a sphere
Valentin Benedetti, Lucas Daguerre
We study the universal logarithmic coefficient of the entanglement entropy (EE) in a sphere for free fermionic field theories in a Minkowski spacetime. As a warm-up, we revis…
Generalized Symmetries For Generalized Gravitons
Valentin Benedetti, Pablo Bueno, Javier M. Magan
We construct generalized symmetries for linearized Einstein gravity in arbitrary dimensions. First-principle considerations in QFT force generalized symmetries to appear in dual pa…
Charges in the UV completion of neutral electrodynamics
Valentin Benedetti, Horacio Casini, Javier M. Magan
A theory with a non-compact form-symmetry is described by two closed form fields of degrees k and d-k. Effective theory examples are non-linear electrodynamics, a photon field coup…
Mutual Information of Generalized Free Fields
Valentin Benedetti, Horacio Casini, Pedro J. Martinez
We study generalized free fields (GFF) from the point of view of information measures. We first review conformal GFF, their holographic representation, and the ambiguities in the a…
Generalized symmetries and Noether's theorem in QFT
Valentin Benedetti, Horacio Casini, Javier M. Magan
We show that generalized symmetries cannot be charged under a continuous global symmetry having a Noether current. Further, only non-compact generalized symmetries can be charged u…
Generalized Symmetries of the Graviton
Valentin Benedetti, Horacio Casini, Javier M. Magan
We find the set of generalized symmetries associated with the free graviton theory in four dimensions. These are generated by gauge invariant topological operators that violate Haa…
Entanglement entropy of linearized gravitons in a sphere
Valentin Benedetti, Horacio Casini
We compute the entanglement entropy of a massless spin field in a sphere in flat Minkowski space. We describe the theory with a linearized metric perturbation field an…
