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 field of topological photonics deals with electromagnetic phenomena (specifically the propagation of light in suitable materials) which mimic the behaviour of electrons in topological insulator materials: photonic crystals.
(For more see the references at photonic crystal.)
