Assume we have a solid state hamiltonian, which is ellectrons plus nuclei plus all possible interactions:(adsbygoogle = window.adsbygoogle || []).push({});

H = [itex]T_{el}[/itex] + [itex]V_{el-el}[/itex] + [itex]T_{n}[/itex] + [itex]V_{n-n}[/itex] + [itex]V_{n-el}[/itex]Is it wrong to write down a self-consistent system of Green functions for electrons and phonons?

[itex]G_{el}[/itex]=g + gS[itex]G_{el}[/itex]S operator does the interraction thing.

[itex]G_{ph}[/itex]=g + gS[itex]G_{ph}[/itex]

Looks fair to me, but I've never seen any articles doing this way.
