Entanglement asymmetry characterization of the Chiral Anomaly
Alfred Benedito, German Sierra
Shao et al. recently showed that the 1+1D staggered fermion Hamiltonian admits a whole algebra of lattice operators that flow to the same axial charge in the thermodynamic limit (T…

Information Loss in Generalized Symmetry Breaking
Javier Molina-Vilaplana, Germán Sierra, H. C. Zhang
We present an algebraic and information-theoretic framework for the breaking of generalized, non-invertible symmetries in two spatial dimensions. Such patterns are modeled as inclu…

Visualizing Three-Qubit Entanglement
Alfred Benedito, Germán Sierra
We present a graphical framework to represent entanglement in three-qubit states. The geometry associated with each entanglement class and type is analyzed, revealing distinct stru…
