Higher cup products on hypercubic lattices: application to lattice models of topological phases
Yu-An Chen, Sri Tata
In this paper, we derive the explicit formula for higher cup products on hypercubic lattices, based on the recently developed geometrical interpretation in the simplicial case. We…

Anomalies in (2+1)D fermionic topological phases and (3+1)D path integral state sums for fermionic SPTs
Sri Tata, Ryohei Kobayashi, Daniel Bulmash +1
Given a (2+1)D fermionic topological order and a symmetry fractionalization class for a global symmetry group , we show how to construct a (3+1)D topologically invariant path in…
