    Experimental realization of strong effective magnetic fields in optical superlattice potentials

    We present the experimental generation of large effective magnetic fields for ultracold atoms using photon-assisted tunneling in an optical superlattice. The underlying method does not rely on the internal str...

    Measuring the Chern number of Hofstadter bands with ultracold bosonic atoms

    Chern numbers characterize the quantum Hall effect conductance—non-zero values are associated with topological phases. Previously only spotted in electronic systems, they have now been measured in ultracold at...
