Measuring topology in a laser-coupled honeycomb lattice: From Chern insulators to topological semi-metals

N. Goldman, E. Anisimovas, F. Gerbier +3

Ultracold fermions trapped in a honeycomb optical lattice constitute a versatile setup to experimentally realize the Haldane model [Phys. Rev. Lett. 61, 2015 (1988)]. In this syste…
