30. Although the experimentally relevant electron density is n ∼ 0.5, the study of higher n values had the sole purpose of verifying the consistency of our results and interpretation for a larger set of qualitatively similar FS geometries to ascertain that the results did not depend fundamentally on some detail of the FS. Our results lead to the same interpretation for the full range of density values analyzed.
31. Note that in Ref. [Fig., n = 0.5], there are small pockets around the (π, 0) points. To obtain these pockets, hopping matrix elements to considerably larger distances have to be added to the Hamiltonian considered here. The authors of Ref. ascertained that the presence or not of these pockets does not alter the main RPA results (private communication).
