Problem of Thermally Driven Diffusion in Terms of Occupation Numbers

Authors: I. V. Drozdov

In the new approach to the diffusion problem conventional statistical derivation is reconsidered deterministically using the partition function for thermal velocities. The resulting relation for time evolution of particle distribution is an integro-differential equation. Its first approximation provides the conventional partial differential equation - the second Fick's law with the diffusion transport coefficient proportional to the temperature.
