The Index of Disordered Topological Insulators with Time Reversal Symmetry
Hosho Katsura, Tohru Koma
We study disordered topological insulators with time reversal symmetry. Relying on the noncommutative index theorem which relates the Chern number to the projection onto the Fermi…

Topological Current in Fractional Chern Insulators
Tohru Koma
We consider interacting fermions in a magnetic field on a two-dimensional lattice with the periodic boundary conditions. In order to measure the Hall current, we apply an electric…
