Spin-orbit coupling in two-dimensional systems is usually characterized by Rashba and Dresselhaus spin-orbit coupling (SOC) linear in the wave vector. However, there is a …
In situ control of spin-orbit coupling in coherent transport using a clean G a A s/A l G a A s two-dimensional electron gas is realized, leading to a gate-tunable crossover from weak …

We investigate heavy-hole spin relaxation and decoherence in quantum dots in perpendicular magnetic fields. We show that at low temperatures the spin decoherence time …
We demonstrate that the Berry curvature monopole of nonmagnetic two-dimensional spin- 3/2 holes leads to a novel Hall effect linear in an applied in-plane magnetic field B∥ …
