Query: Generalized Elliott-Yafet spin-relaxation time for arbitrary spin mixing   We extend our recent result for the spin-relaxation time due to acoustic
electron-phonon scattering in degenerate bands with spin mixing [New J. Phys.
18, 023012 (2015)] to include interactions with optical phonons, and present a
numerical evaluation of the spin-relaxation time for intraband hole-phonon
scattering in the heavy-hole (HH) bands of bulk GaAs. Comparing our computed
spin-relaxation times to the conventional Elliott-Yafet result quantitatively
demonstrates that the latter underestimates the spin-relaxation time because it
does not correctly describe how electron-phonon interactions change the
(vector) spin expectation value of the single-particle states. We show that the
conventional Elliott-Yafet spin relaxation time is a special case of our result
for weak spin mixing.
