WebMar 6, 2024 · We classify the possible band structures for all 230 crystal symmetry groups that arise from local atomic orbitals, and show which are topologically nontrivial. We show how our topological band theory sheds new light on known TIs, and demonstrate the power of our method to predict a plethora of new TIs. Submission history WebConcept of Band Structure Andreas Wacker1 Mathematical Physics, Lund University November 20, 2024 1 Introduction Band structure is one of the most important concepts in solid state physics. It provides the electronic levels in (ideal) crystal structures, which are characterized by two quantum numbers, the Bloch vector k and the band index n.
