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…
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…
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…
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…
