On tensor network representations of the (3+1)d toric code
Clement Delcamp, Norbert Schuch
We define two dual tensor network representations of the (3+1)d toric code ground state subspace. These two representations, which are obtained by initially imposing either family…
On the stability of topological order in tensor network states
Dominic J. Williamson, Clement Delcamp, Frank Verstraete +1
We construct a tensor network representation of the 3d toric code ground state that is stable to a generating set of uniform local tensor perturbations, including those that do not…
Gapped boundaries and string-like excitations in (3+1)d gauge models of topological phases
Alex Bullivant, Clement Delcamp
We study lattice Hamiltonian realisations of (3+1)d Dijkgraaf-Witten theory with gapped boundaries. In addition to the bulk loop-like excitations, the Hamiltonian yields bulk dyoni…
Computing the renormalization group flow of two-dimensional theory with tensor networks
Clement Delcamp, Antoine Tilloy
We study the renormalization group flow of theory in two dimensions. Regularizing space into a fine-grained lattice and discretizing the scalar field in a controlled way, we…
