General corner charge formulas in various tetrahedral and cubic space groups
Hidetoshi Wada, Katsuaki Naito, Seishiro Ono +2
In some insulators, corner charges are fractionally quantized, due to the topological invariant called a filling anomaly. The previous theories of fractional corner charges have be…

Fractional hinge and corner charges in various crystal shapes with cubic symmetry
Katsuaki Naito, Ryo Takahashi, Haruki Watanabe +1
Higher-order topological insulators host gapless states on hinges or corners of three-dimensional crystals. Recent studies suggested that even topologically trivial insulators may…
