Applicability of Eliashberg theory for systems with electron-phonon and electron-electron interaction: a comparative analysis
Shang-Shun Zhang, Zachary M. Raines, Andrey V. Chubukov
We present a comparative analysis of the validity of Eliashberg theory for the cases of fermions interacting with an Einstein phonon and with soft nematic fluctuations near an Isin…

Interacting fermions in two dimensions: beyond the perturbation theory
S. Gangadharaiah, D. L. Maslov, A. V. Chubukov +1
We consider a system of 2D fermions with short-range interaction. A straightforward perturbation theory is shown to be ill-defined even for an infinitesimally weak interaction, as…
