22. Although often found in the literature, the way this screening is introduced is in fact inconsistent: it relies on RPA (bubble) processes, dominant at large density, and is used in exciton (ladder) processes dominant at low density: from such a procedure, there is no hope to get more than a qualitative behavior.
