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…
Symmetry topological field theory and non-abelian Kramers-Wannier dualities of generalised Ising models
Clement Delcamp, Nafiz Ishtiaque
For a class of two-dimensional Euclidean lattice field theories admitting topological lines encoded into a spherical fusion category, we explore aspects of their realisations as bo…
