Self-organized exotic lattices with ultracold gases [PDF]
O. Dutta, A. Przysiezna, M. LewensteinWe study an ultracold Fermi-Fermi mixture of strongly attractive atoms trapped in a square lattice. We show that the interaction-induced multi-band nature of such system can change the inherent structure of the original lattice. The dynamically generate lattice resembles geometrically a Lieb lattice with interaction-driven topological insulator phases.View original: http://arxiv.org/abs/1301.4156
