Query: Room temperature spin thermoelectrics in metallic films   Considering metallic films at room temperature, we present the first
theoretical study of the spin Nernst and thermal Edelstein effects which takes
into account dynamical spin-orbit coupling, i.e., direct spin-orbit coupling
with the vibrating lattice (phonons) and impurities. This gives rise to two
novel processes, namely a dynamical Elliott-Yafet spin relaxation and a
dynamical side-jump mechanism. Both are the high-temperature counterparts of
the well-known $T = 0$ Elliott-Yafet and side-jump, central to the current
understanding of the spin Hall, spin Nernst and Edelstein effects at low $T$.
We consider the experimentally relevant regime $T > T_D$, with $T_D$ the Debye
temperature, as the latter is lower than room temperature in transition metals
such as Pt, Au and Ta typically employed in spin injection/extraction
experiments. We show that the interplay between intrinsic (Bychkov-Rashba type)
and extrinsic (dynamical) spin-orbit coupling yields a nonlinear $T$-
dependence of the spin Nernst and spin Hall conductivities.
