No - the transport equations are only provided in a cubic symmetry approximation (1 direction for the electric field and isotropy of the resistance tensor is assumed). The resistance etc.. as a function of T are given as in the paper by Savrasov and Savrasov (prb 1996) in a crude approximation to the Boltzmann equations.

Dear All,
           is it possible to use the response function capabilities of Abinit
to obtain the directional dependence of the Eliashberg function so that it can
be used to calculate transport properties using the Bloch-Gruneisen equation?

In the response function tutorials I could only see information on the full
Eliashberg function.

I would like to calculate the resistivity as a function of Temperature for my
metallic system to see how great the influence of phonons is.

Thank you,
David.
