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…

Algebras of order parameters in one-dimensional spin systems

Ameya Chavda, Clement Delcamp, Alex Turzillo +1

We study order parameters in one-dimensional quantum lattice models with finite invertible or non-invertible symmetry. We investigate what properties a string operator must satisfy…

Gauging Non-Invertible Symmetries in (2+1)d Topological Orders

Mahesh K. N. Balasubramanian, Matthew Buican, Clement Delcamp +1

We present practical and formal methods for gauging non-invertible symmetries in (2+1)d topological quantum field theories. Along the way, we generalize various aspects of invertib…

Twisted gauging and topological sectors in (2+1)d abelian lattice gauge theories

Bram Vancraeynest-De Cuiper, Clement Delcamp

Given a two-dimensional quantum lattice model with an abelian gauge theory interpretation, we investigate a duality operation that amounts to gauging its invertible 1-form symmetry…

A non-semisimple non-invertible symmetry

Clement Delcamp, Edmund Heng, Matthew Yu

We investigate the action of a non-invertible symmetry on spins chains whose topological lines are labelled by representations of the four-dimensional Taft algebra. The main peculi…

Entanglement and the density matrix renormalisation group in the generalised Landau paradigm

Laurens Lootens, Clement Delcamp, Frank Verstraete

The fields of entanglement theory and tensor networks have recently emerged as central tools for characterising quantum phases of matter. In this article, we determine the entangle…
