Topological phase transition in bulk materials described by the coherent potential approximation technique

Investigation of the nonlocal coherent-potential approximation

Recently the nonlocal coherent-potential approximation (NLCPA) has been introduced by Jarrell and Krishnamurthy for describing the electronic structure of substitutionally-disordered systems. The NLCPA provides systematic corrections to the widely used coherent-potential approximation (CPA) whilst preserving the full symmetry of the underlying lattice. Here an analytical and systematic numerica...

CORRIGENDUM: Topological Phase Transition without Gap Closing

This Article contains typographical errors in the Results and Discussion sections, where ‘‘A’’ should read ‘‘AI’’. In the Results section: ‘‘(BDI R A R BDI)’’ should read ‘‘(BDI R AI R BDI)’’ In the Discussion section: ‘‘BDI R A’’ should read ‘‘BDI R AI’’ ‘‘(BDI R A R BDI)’’ should read ‘‘(BDI R AI R BDI)’’ In addition, the red line between BDI andA should be between BDI andAI. The correct Figu...
