General corner charge formula in two-dimensional -symmetric higher-order topological insulators
In this paper, we derive a general formula for the quantized fractional corner charge in two-
dimensional C n-symmetric higher-order topological insulators. We assume that the …

Bound states at partial dislocation defects in multipole higher-order topological insulators
The bulk-boundary correspondence, which links a bulk topological property of a material to
the existence of robust boundary states, is a hallmark of topological insulators. However, in …

-band Hopf insulator
We study the generalization of the three-dimensional two-band Hopf insulator to the case of
many bands, where all the bands are separated from each other by band gaps. The …

Homotopic classification of band structures: Stable, fragile, delicate, and stable representation-protected topology
PW Brouwer, V Dwivedi - Physical Review B, 2023 - APS
The topological classification of gapped band structures depends on the particular definition
