Spin transport is solely due to the spin-torque current in this strongly spin-orbit coupled (SOC) system, and chiral spin-flip scattering off non-SOC scalar impurities, with potential strength $V$ and size $a$, gives rise to a skew-scattering mechanism for the spin Hall effect. The key result is that the resultant spin-Hall angle has a fixed sign, with $\\theta^{SH} \\sim O \\left(\\tfrac{V^2}{v_F^2/a^2} (k_F a)^4 \\right)$ being a strongly-dependent funct","authors_text":"Naoto Nagaosa, T.
