Spin and valley Hall effects induced by asymmetric interparticle scattering

The physics of spin currents has always attracted the attention Professor Rashba who made seminal contributions to field. Here, authors develop theory and valley Hall effects in systems interacting fermions bosons. In high-mobility two-dimensional semiconductors, interparticle scattering dominates over impurity phonon controls transport effects. demonstrate theoretically that collisions between quasiparticles give rise via skew-scattering effect. They also calculate efficiency such a process.
