Excitations in strict 2-group higher gauge models of topological phases
Alex Bullivant, Clement Delcamp
We consider an exactly solvable model for topological phases in (3+1)d whose input data is a strict 2-group. This model, which has a higher gauge theory interpretation, provides a…

Tube algebras, excitations statistics and compactification in gauge models of topological phases
Alex Bullivant, Clement Delcamp
We consider lattice Hamiltonian realizations of (+1)-dimensional Dijkgraaf-Witten theory. In (2+1)d, it is well-known that the Hamiltonian yields point-like excitations classifi…

On 2-form gauge models of topological phases
Clement Delcamp, Apoorv Tiwari
We explore various aspects of 2-form topological gauge theories in (3+1)d. These theories can be constructed as sigma models with target space the second classifying space o…
