  We explicitly show that the differences, with respect to the appearance of
topological phases, between the traditional Haldane model, which utilises a
honeycomb lattice structure, to that of the Haldane model imbued onto a
brick-wall lattice geometry, are inconsequential. A proposal is then put
forward to realise the Haldane model by exploiting the internal degrees of
freedom of atoms as a synthetic dimension. This leads to a convenient platform
for the investigation of chiral edge states due to the hard boundaries provided
by the hyperfine manifold. We make some cursory comments on the effects of
interactions in the system.
