Topological to trivial insulating phase transition in stanene

Caged clusters in Al11Ir4: Structural transition and insulating phase

Using pair potentials fitted to an ab initio database, combined with replica-exchange simulated annealing, we show that the complex, quasicrystal-related Al11Ir4 compound contains a nonstandard version of the “pseudo-Mackay” icosahedral cluster, with nonicosahedral inner Al10Ir and/or Al9Ir clusters that exist in various orientations and account for partial occupancies in the reported structure...

Pressure induced Ag2Te polymorphs in conjunction with topological non trivial to metal transition

Transition to a Superconductor with Insulating Cavities

– An extreme type II superconductor with internal insulating regions, namely cavities, is studied here. We find that the cavity-bearing superconductor has lower energy than the defectfree superconductor above a critical magnetic induction B∗ for insulating cavities but not for metallic ones. Using a numerical approach for the Ginzburg-Landau theory we compute and compare free energy densities f...

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...

Topological Phase Transition without Gap Closing

Topological phase transition is accompanied with a change of topological numbers. According to the bulk-edge correspondence, the gap closing and the breakdown of the adiabaticity are necessary at the phase transition point to make the topological number ill-defined. However, the gap closing is not always needed. In this paper, we show that two topological distinct phases can be continuously con...
