Topological Physics – Phenomena in physics controlled by the topology (often: the homotopy theory) of the physical system.
General theory:
In metamaterials:
topological phononics (sound waves?)
For quantum computation:
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.
Discussion of line defects and the loop braid group statistics, with application to topological phases of matter using higher gauge theory/higher parallel transport:
