WebJun 17, 2024 · Remarkably, the filling enforced criteria enable the identification of obstructed atomic bands without knowing the representations of the band structures. Hence, no ab-initio calculations are needed for the filling enforced criteria, although they are needed to obtain the band gaps. WebTopological band insulators and (semi-) metals can arise out of atomic insulators when the hopping strength between electrons increases. Such topological phases are separated from the atomic insulator by a bulk gap closing. In this work, we show that in many (magnetic) space groups, the crystals with certain Wyckoff positions and orbitals being …
WebOct 26, 2024 · Here, using the TQC theory, we present an intuitive argument about the connection between the obstructed Wannier charge centers of OAIs and the emergence of robust corner states in two-dimensional systems. Based on first-principles calculations and Real Space Invariant theory, we extend the concept of OAIs to phonon systems and … WebIn (f), the highest valence band and the lowest conduction band are separated by a large band gap, and the (100) surface is insulating. On the other hand, the valence and conduction bands on the (001) surface are degenerate at the high-symmetry points, and the (001) surface in (d) is metallic. - "Filling-Enforced Obstructed Atomic Insulators"
