Topological lattice gauge theory enriched by non-invertible symmetry
Lea E. Bottini, Clement Delcamp, Edmund Heng +2
We use finite group topological lattice gauge theory, also known as the quantum double model, as a lens to explore a notion of topological order enriched by a non-invertible symmet…

Classifying one-dimensional Floquet phases through two-dimensional topological order
Campbell McLauchlan, Vedant Motamarri, Benjamin Béri
Floquet systems display rich phenomena, such as time crystals, with many-body localisation (MBL) protecting the phases from heating. While several types of Floquet phases have been…

Accommodating Fabrication Defects on Floquet Codes with Minimal Hardware Requirements
Campbell McLauchlan, György P. Gehér, Alexandra E. Moylett
Floquet codes are an intriguing generalisation of stabiliser and subsystem codes, which can provide good fault-tolerant characteristics while benefiting from reduced connectivity r…
