LOCALIZED ENDOMORPHISMS IN KITAEV'S TORIC CODE ON THE PLANE
LOCALIZED ENDOMORPHISMS IN KITAEV'S TORIC CODE ON THE PLANE
We consider various aspects of Kitaev's toric code model on a plane in the C*-algebraic approach to quantum spin systems on a lattice. In particular, we show that elementary excitations of the ground state can be described by localized endomorphisms of the observable algebra. The structure of these endomorphisms is …
