Hinge states in a system of coupled Rashba layers
We consider a system of stacked tunnel-coupled two-dimensional electron- and hole-gas layers with Rashba spin-orbit interaction subjected to a staggered Zeeman field. The interplay of different intralayer tunnel couplings results in a topological insulator phase characterized by the presence of gapl...
