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…
Entropic order parameters and topological holography
Hua-Chen Zhang, Germán Sierra, Javier Molina-Vilaplana
We show that the symmetry topological field theory (SymTFT) construction, also known as the topological holography, provides a natural and intuitive framework for the entropic orde…
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…
Entropic Order Parameters for Categorical Symmetries in 2D-CFT
Javier Molina-Vilaplana, Pablo Saura-Bastida, Germán Sierra
In this work, we propose an information theoretic order parameter able to characterize the presence and breaking of categorical symmetries in (1 + 1)-d rational conformal field the…
Categorical-Symmetry Resolved Entanglement in CFT
P. Saura-Bastida, A. Das, G. Sierra +1
We propose a symmetry resolution of entanglement for categorical non-invertible symmetries (CaT-SREE) in (1 + 1)-dimensional CFTs. The definition parallels that of group-like inver…
