Disentangling supercohomology symmetry-protected topological phases in three spatial dimensions
Yu-An Chen, Tyler D. Ellison, Nathanan Tantivasadakarn
Abstract
The authors use a series of lattice dualities to build exactly solvable models for supercohomology symmetry-protected topological phases in (3+1)-dimensions. They also construct gapped topologically ordered boundaries for the fermionic models by extending the global symmetry.
