Model of the Peltier spin effect in nonmagnetic chiral conductors

It is shown that in a polycrystalline conductor with a helicity chiral structure and a strong spin-orbit interaction, the generation of a longitudinally polarized spin current and the heat flux associated with it are possible. At a given density of the charge current, the heat flux density depends on the local temperature, but not on its gradient, and is proportional to the lattice thermal conductivity coefficient.
