Higher-form entanglement asymmetry. Part I. The limits of symmetry breaking
Francesco Benini, Eduardo GarcÃa-Valdecasas, Stathis Vitouladitis
Entanglement asymmetry is a relative entropy that faithfully diagnoses symmetry breaking in quantum states, possibly within a spatial subregion. In this work, we extend such framew…
Entanglement asymmetry for higher and noninvertible symmetries
Francesco Benini, Pasquale Calabrese, Michele Fossati +2
Entanglement asymmetry is an observable in quantum systems, constructed using quantum-information methods, suited to detecting symmetry breaking in states -- possibly out of equili…
Entanglement asymmetry in conformal field theory and holography
Francesco Benini, Victor Godet, Amartya Harsh Singh
Entanglement asymmetry is a measure of symmetry breaking in quantum subsystems, inspired by quantum information theory, particularly suited to study out-of-equilibrium states. We s…
Anomalies and gauging of U(1) symmetries
Andrea Antinucci, Francesco Benini
We propose the Symmetry TFT for theories with a symmetry in arbitrary dimension. The Symmetry TFT describes the structure of the symmetry, its anomalies, and the possible to…
Holographic duals of symmetry broken phases
Andrea Antinucci, Francesco Benini, Giovanni Rizi
We explore a novel interpretation of Symmetry Topological Field Theories (SymTFTs) as theories of gravity, proposing a holographic duality where the bulk SymTFT (with the gauging o…
On the Symmetry TFT of Yang-Mills-Chern-Simons theory
Riccardo Argurio, Francesco Benini, Matteo Bertolini +2
Three-dimensional Yang-Mills-Chern-Simons theory has the peculiar property that its one-form symmetry defects have non-trivial braiding, namely they are charged under the same symm…
