Topological Floquet engineering using two frequencies in two dimensions
Yixiao Wang, Anne-Sophie Walter, Gregor Jotzu +1
Using two-frequency driving in two dimensions opens up new possibilites for Floquet engineering, which range from controlling specific symmetries to tuning the properties of resona…
Enhancement and sign change of magnetic correlations in a driven quantum many-body system
Frederik Görg, Michael Messer, Kilian Sandholzer +3
Periodic driving can be used to coherently control the properties of a many-body state and to realize new phases which are not accessible in static systems. For example, exposing m…
Controlling the Floquet state population and observing micromotion in a periodically driven two-body quantum system
Rémi Desbuquois, Michael Messer, Frederik Görg +3
Near-resonant periodic driving of quantum systems promises the implementation of a large variety of novel effective Hamiltonians. The challenge of Floquet engineering lies in the p…
Creating topological interfaces and detecting chiral edge modes in a 2D optical lattice
N. Goldman, G. Jotzu, M. Messer +3
We propose and analyze a general scheme to create chiral topological edge modes within the bulk of two-dimensional engineered quantum systems. Our method is based on the implementa…
Formation and dynamics of anti-ferromagnetic correlations in tunable optical lattices
Daniel Greif, Gregor Jotzu, Michael Messer +2
We report on the observation of anti-ferromagnetic correlations of ultracold fermions in a variety of optical lattice geometries that are well described by the Hubbard model, inclu…
Creating State-Dependent Lattices for Ultracold Fermions by Magnetic Gradient Modulation
Gregor Jotzu, Michael Messer, Frederik Görg +3
We demonstrate a versatile method to create state-dependent optical lattices by applying a magnetic field gradient modulated in time. This allows for tuning the relative amplitude…
