What's Done Cannot Be Undone: TASI Lectures on Non-Invertible Symmetry

SH Shao - arXiv preprint arXiv:2308.00747, 2023 - arxiv.org
We survey recent developments in a novel kind of generalized global symmetry, the non-
invertible symmetry, in diverse spacetime dimensions. We start with several different but …

Non-invertible symmetries and LSM-type constraints on a tensor product Hilbert space

N Seiberg, S Seifnashri, SH Shao - SciPost Physics, 2024 - scipost.org
We discuss the exact non-invertible Kramers-Wannier symmetry of 1+ 1d lattice models on a
tensor product Hilbert space of qubits. This symmetry is associated with a topological defect …

Lattice realizations of topological defects in the critical (1+ 1)-d three-state Potts model

M Sinha, F Yan, L Grans-Samuelsson, A Roy… - Journal of High Energy …, 2024 - Springer
A bstract Topological/perfectly-transmissive defects play a fundamental role in the analysis
of the symmetries of two dimensional conformal field theories (CFTs). In the present work …

Majorana chain and Ising model-(non-invertible) translations, anomalies, and emanant symmetries

N Seiberg, SH Shao - SciPost Physics, 2024 - scipost.org
We study the symmetries of closed Majorana chains in 1+ 1d, including the translation,
fermion parity, spatial parity, and time-reversal symmetries. The algebra of the symmetry …

Nonintegrable Floquet Ising model with duality twisted boundary conditions

A Mitra, HC Yeh, F Yan, A Rosch - Physical Review B, 2023 - APS
Results are presented for a Floquet Ising chain with duality twisted boundary conditions,
taking into account the role of weak integrability breaking in the form of four-fermion …

Duality defect in a deformed transverse-field Ising model

F Yan, R Konik, A Mitra - arXiv preprint arXiv:2410.17317, 2024 - arxiv.org
Physical quantities with long lifetimes have both theoretical significance in the study of
quantum many-body systems and practical implications for quantum technologies. In this …

Isolated Majorana mode in a quantum computer from a duality twist

S Samanta, DS Wang, A Rahmani, A Mitra - arXiv preprint arXiv …, 2023 - arxiv.org
Experimental investigation of the interplay of dualities, generalized symmetries, and
topological defects is an important challenge in condensed matter physics and quantum …

Tensor networks for non-invertible symmetries in 3+ 1d and beyond

P Gorantla, SH Shao, N Tantivasadakarn - arXiv preprint arXiv …, 2024 - arxiv.org
Tensor networks provide a natural language for non-invertible symmetries in general
Hamiltonian lattice models. We use ZX-diagrams, which are tensor network presentations of …

Duality-preserving deformation of 3+1d lattice gauge theory with exact gapped ground states

P Gorantla, TC Huang - arXiv preprint arXiv:2409.10612, 2024 - arxiv.org
We propose and analyze a deformation of the 3+ 1d lattice $\mathbb Z_2 $ gauge theory
that preserves the non-invertible Wegner duality symmetry at the self-dual point. We identify …
