Description:
Author(s): Nicolai Lang and Hans Peter Büchler Motivated by the question of topological classification in interacting models the authors study an exactly solvable two-leg ladder model of spinless fermions with attractive interactions and find its ground states and correlation functions. They also demonstrate the appearance of topologically protected edge states and derive their braiding properties on a microscopic level. [Phys. Rev. B 92, 041118(R)] Published Wed Jul 29, 2015
