Classifying fractionalization: symmetry classification of gapped Z2 spin liquids in two dimensions
Andrew M. Essin, Michael Hermele
We classify distinct types of quantum number fractionalization occurring in two-dimensional topologically ordered phases, focusing in particular on phases with Z2 topological order…

Topological invariants and interacting one-dimensional fermionic systems
Salvatore R. Manmana, Andrew M. Essin, Reinhard M. Noack +1
We study one-dimensional, interacting, gapped fermionic systems described by variants of the Peierls-Hubbard model and characterize their phases via a topological invariant constru…
