Some Topological Aspects of Condensed Matter Physics
The angular momentum paradox in Helium 3 is revisited. The edge currents in an infinite half plane and in a cylinder are calculated using the Bogoliubov de Gennes approximation and are shown to be consistent with the expectation of an unit of angular momentum associated with every Cooper pair. The …
