Perturbative approach to flat Chern bands in the Hofstadter model
We present a perturbative approach to the study of the Hofstadter model for when the

Emergence of a Landau level structure in dark optical lattices
S Nascimbene, J Dalibard - arxiv preprint arxiv:2412.15038, 2024 - arxiv.org
An optical flux lattice is a set of light beams that couple different internal states of an atom,
thereby producing topological energy bands. Here we present a configuration in which the …
