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…
Global anomaly detection in two-dimensional symmetry-protected topological phases
Nick Bultinck, Robijn Vanhove, Jutho Haegeman +1
Edge theories of symmetry-protected topological phases are well-known to possess global symmetry anomalies. In this work we focus on two-dimensional bosonic phases protected by an…
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…
