Stoner transitions beyond mean-field in two-dimensional electronic systems: a diagrammatic Monte Carlo study
Yueh-Chen Lee, Nikolay V. Prokof'ev, Andrey V. Chubukov
Stoner instabilities for fermions with repulsive interaction have been well studied within the mean-field (ladder) approximation. In this study, we consider two-dimensional electro…
Breakdown of the Migdal-Eliashberg theory for electron-phonon systems. Role of polarons/bi-polarons
Andrey Chubukov, Ilya Esterlis, Artem Abanov +1
The Migdal-Eliashberg theory (MET) describes electrons interacting with phonons in the adiabatic limit when the phonon Debye frequency is much smaller than the Fermi energy. A conv…
Limits of validity for Migdal-Eliashberg theory: role of polarons/bi-polarons
Nikolay Prokof'ev, Ilya Esterlis, Artem Abanov +1
It is widely believed that in the adiabatic limit the Fermi liquid state of an electron-phonon system, described by Migdal-Eliashberg theory, remains stable until the dressed phono…
Superconductivity in Electron Liquids: Precision Many-Body Treatment of Coulomb Interaction
Xiansheng Cai, Tao Wang, Shuai Zhang +5
More than a century after discovery, the theory of conventional superconductivity remains incomplete. While the importance of electron-phonon coupling is understood, a controlled f…
