Out-of-plane spin polarization of edge currents in Chern insulator with Rashba spin-orbit interaction

Tsung-Wei Chen, Chin-Lun Hsiao, Chong-Der Hu

We investigate the change in the non-zero Chern number and out-of-plane spin polarization of the edge currents in a honeycomb lattice with the Haldane-Rashba interaction. This inte…
