The Creutz-Hubbard ladder: a multi-purpose setup — •Matteo Rizzi — Institute for Theoretical Physics, Universität zu Köln, Germany — Institute for Quantum Control (PGI-8), Forschungszentrum Jülich, Germany

We briefly review recent contribution of ours about the Creutz Hubbard ladder, which allows to explore topological flat bands and undoubled Dirac cones, (symmetry-protected) fractional interacting phases as well as exotic transport properties, all in a single tunable setup. We provide experimental recipes for cold atomic gases. We employ analytical mappings onto effective models and numerical tensor networks calculations, thereby computing static and dynamical observables and entanglement properties, too.
