Topological nonlinear σ -model, higher gauge theory, and a systematic construction of 3 + 1 D topological orders for boson systems
© 2019 American Physical Society. A discrete nonlinear σ-model is obtained by triangulate both the space-time Md+1 and the target space K. If the path integral is given by the sum of all the simplicial homomorphisms φ:Md+1→K (i.e., maps without any topological defects), with an partition function th...
