Dynamical generalization of Yetter’s model based on a crossed module of discrete groups
Abstract We construct a lattice model based on a crossed module of possibly non-abelian finite groups. It generalizes known topological quantum field theories, but in contrast to these models admits local physical excitations. Its degrees of freedom are defined on links and plaquettes, while gauge t...
