Spin-orbit coupling effects in a kagome scattering network — •Patrick Wittig1, Fernando Dominguez1, and Patrik Recher1,2 — 1Institute of Mathematical Physics, TU Braunschweig, 38106 Braunschweig, Germany — 2Laboratory of Emerging Nanometrology, 38106 Braunschweig, Germany
Recently, scattering networks have gained a lot of attention, because they can model two-dimensional Dirac systems that are dominated by valley chiral modes. Here, we study the kagome scattering network that has been proposed in double-aligned graphene-hexagonal boron nitride [1,3] and periodically strained graphene [2]. By combining scattering matrices, we transform the kagome network to a triangular network with an energy-dependent scattering matrix and perform magnetotransport calculations. Additionally, due to the recent interest in proximity-induced spin-orbit effects in graphene, we include spin-orbit coupling in the scattering network model.
