Topological Mott insulators of ultracold atomic mixtures induced by interactions in one-dimensional optical superlattices

We present exactly solvable examples showing that topological Mott insulators can emerge from topologically trivial states due to strong interactions between atoms for atomic mixtures trapped in one-dimensional optical superlattice systems. The topological Mott insulating state is characterized by a...
