Symmetry-enriched topological order in tensor networks: Defects, gauging and anyon condensation
Dominic J. Williamson, Nick Bultinck, Frank Verstraete
We study symmetry-enriched topological order in two-dimensional tensor network states by using graded matrix product operator algebras to represent symmetry-induced domain walls. A…
Fermionic projected entangled-pair states and topological phases
Nick Bultinck, Dominic J. Williamson, Jutho Haegeman +1
We study fermionic matrix product operator algebras and identify the associated algebraic data. Using this algebraic data we construct fermionic tensor network states in two dimens…
Anomalies and entanglement renormalization
Jacob C. Bridgeman, Dominic J. Williamson
We study 't Hooft anomalies of discrete groups in the framework of (1+1)-dimensional multiscale entanglement renormalization ansatz states on the lattice. Using matrix product oper…
