nLab Walker-Wang model




The Walker-Wang model is a model (in theoretical physics) which is a 4d TQFT analog of the Levin-Wen model 3d TQFT. It is the Hamiltonian formulation of the TQFT whose partition function formulation is the Crane-Yetter model. It is speculated to have some application to topological insulators in solid state physics.
