2D Electron Gas Subject to Inhomogeneous Magnetic Fields: Current Oscillations, the Role of Spin and Non-Landau Quantization

We demonstrate numerical and analytical results for a 2D electron gas in an inhomogeneous magnetic field. The coexistence of solid state and atomistic properties is caused by field induced localisation effects. In contrast to the paradigmatic Landau setting for homogeneous magnetic fields, we will demonstrate that the Zeeman (Spin) interaction becomes a highly relevant contribution, which gives rise to non-trivial orbital and spin currents. Resulting modifications of the Landau level structure and emerging density fluctuations are investigated.
