The H^2 fermionic ’t Hooft anomaly as a Kitaev-chain-layer anomaly
Let $G$ be the symmetry group, and let an anomalous $2+1$ D fermionic symmetry-enriched topological phase have obstruction in $H^2(G,\mathbb{Z}_2)$ . A Kitaev chain layer is the bulk…

Kapustin's conjecture on the classification of interacting fermionic SPT phases
The symmetry class under consideration has an integer free-fermion classification that is reduced to $\mathbb{Z}_8$ by interactions. Kapustin's classification conjecture. There are…
