a, b Spectral decomposition at different values of chemical potential when an electric field \(\overrightarrow{E}\) is applied along the z and the x axis, respectively. The spectral amplitudes are color-coded, and white dots show the calculated spin relaxation rate. For \(\overrightarrow{E}\parallel z\) and energy E = −20 meV, c shows the spectrum, and d the spin density time dependence, normalized as charge-to-spin conversion efficiency. e The non-equilibrium deviation of the total distribution function δfk calculated near energies −5 meV (inner contour) and -20 meV (outer contour). f, g Contributions to δfk from relaxons with Γi > 0.33 and Γi < 0.33, respectively.
