Band inversion and topological phase transition.

(a,b) Current densities in the pseudospin-up channel (p+ or d+) and pseudospin-down channel (p− or d−) respectively. Band dispersions for the system given in Fig. 1: (c) t1 = 0.9t0 (Inset: Brillouin zone of the triangular lattice), (d) t1 = t0 and (e) t1 = 1.1t0. Blue and red are for |p±〉 and |d±〉 orbitals respectively and rainbow for hybridization between them. The on-site energy is taken ε0 = 0.
