Ising anyonic topological phase of interacting Fermions in one dimension
Kai Guther, Nicolai Lang, Hans Peter Büchler
We study a microscopic model of interacting fermions in a ladder setup, where the total number of particles is conserved. At a special point, the ground state is known and gives ri…

Topological states in a microscopic model of interacting fermions
Nicolai Lang, Hans Peter Büchler
We present a microscopic model of interacting fermions where the ground state degeneracy is topologically protected. The model is based on a double-wire setup with local interactio…
