Cluster state as a noninvertible symmetry-protected topological phase

S Seifnashri, SH Shao - Physical Review Letters, 2024 - APS
We show that the standard 1+ 1 DZ 2× Z 2 cluster model has a noninvertible global
symmetry, described by the fusion category Rep (D 8). Therefore, the cluster state is not only …

Gapped phases with non-invertible symmetries:(1+ 1) d

L Bhardwaj, LE Bottini, D Pajer, S Schäfer-Nameki - SciPost Physics, 2025 - scipost.org
We propose a general framework to characterize gapped infra-red (IR) phases of theories
with non-invertible (or categorical) symmetries. In this paper we focus on (1+ 1) d gapped …

Gauging modulated symmetries: Kramers-Wannier dualities and non-invertible reflections

SD Pace, G Delfino, HT Lam, ÖM Aksoy - SciPost Physics, 2025 - scipost.org
Modulated symmetries are internal symmetries that act in a non-uniform, spatially modulated
way and are generalizations of, for example, dipole symmetries. In this paper, we …

Some aspects of symmetry descent

IG Etxebarria, SS Hosseini - Journal of High Energy Physics, 2025 - Springer
A bstract In many cases the symmetry structure of quantum field theories can be neatly
encoded into their associated symmetry topological field theory (SymTFT), a topological field …

Illustrating the Categorical Landau Paradigm in Lattice Models

Recent years have seen the concept of global symmetry extended to non-invertible (or
categorical) symmetries, for which composition of symmetry generators is not necessarily …

Generating Lattice Non-invertible Symmetries

W Cao, L Li, M Yamazaki - arxiv preprint arxiv:2406.05454, 2024 - arxiv.org
Lattice non-invertible symmetries have rich fusion structures and play important roles in
understanding various exotic topological phases. In this paper, we explore methods to …
