<Martin Lebrat> coauthored a controlled realization of the <Haldane model> with <ultracold gases>. Periodic lattice motion and an adjustable offset between neighboring sites independently controlled two symmetry-breaking effects.
The team located the topological transition by finding where the energy gap closed at a single <Dirac point>. This made the boundary between distinct quantum phases an experimentally measured relation between adjustable parameters.<Experimental realisation of the topological Haldane model by Gregor Jotzu and others>[Abstract: competing controls and single-Dirac-point gap closure]{ref}
