Fractional Corner Charge of Sodium Chloride
Recent developments in higherorder topological phases have revealed the relationship between nontrivial multipole moments in the bulk and the emergence of fractionally quantized charges at the boundary. Here, we put forth a proposal of the three-dimensional octupole insulator with fractionally quant...
