Abstract: Detailed analyses of the spin and orbital conductivities are performed for different topological phases of certain classes of two-dimensional multiorbital materials. Our calculations show the existence of orbital-Hall effect (OHE) in topological insulators, with values… read more here.

DOI: 10.1103/physrevb.96.245135
Abstract: We consider the interacting, spin conserving, extended Kane-Mele-Hubbard model, and we rigorously establish the exact quantization of the edge spin conductance and the validity of the Helical Luttinger liquid relations for Drude weights and susceptibilities.… read more here.
