<Daniel Greif> coauthored the atomic realization of the <Haldane model>. The experiment used driven <fermions> in an optical <honeycomb lattice> to produce topologically distinct <energy bands>.
Applying a constant <force> produced transverse drift related to <Berry curvature>. This linked the geometry of a quantum band to measured atomic <motion>, complementing the direct measurement of the energy gap.<Experimental realisation of the topological Haldane model by Gregor Jotzu and others>[Abstract: band-gap measurements and transverse drift]{ref}
