Query: Chern insulator in a ferromagnetic two-dimensional electron system with
  Dresselhaus spin-orbit coupling   We propose a Chern insulator in a two-dimensional electron system with
Dresselhaus spin-orbit coupling, ferromagnetism, and spin-dependent effective
mass. The analytically-obtained topological phase diagrams show the topological
phase transitions induced by tuning the magnetization orientation with the
Chern number varying between $1,0,-1$. The magnetization orientation tuning
shown here is a more practical way of triggering the topological phase
transitions than manipulating the exchange coupling that is no longer tunable
after the fabrication of the system. The analytic results are confirmed by the
band structure and transport calculations, showing the feasibility of this
theoretical proposal. With the advanced and mature semiconductor engineering
today, this Chern insulator is very possible to be experimentally realized and
also promising to topological spintronics.
