The transport coefficients can be evaluated rather straightforwardly under the approximation of the constant relaxation time. The most computationally demanding part of the calculation is the electronic linewidths due to the electron-phonon scattering. As such, it is instructive to start by computing the transport coefficients in the constant-relaxation time appr..."

This calculation is activated by default when {{TAG|ELPH_RUN}}=.TRUE. and {{TAG|ELPH_DRIVER}}=EL. For the particular case where we want to determine the bandgap we can compute the self-energy only for the states that form the gap (including all the degenerate states). The selection of these s..."

Electron-phonon coupling refers to the coupling of these two systems, and can be used to include the effect of each other when treating the two systems separately. The inclusion of the effects of the ionic degrees of freedom in the electronic structure is important in the determination of many physical observables such as the bandgap, spectral f..."
