Does a pole in the self-energy imply a violation of the Luttinger theorem?
Artem Abanov, Andrey Chubukov
Luttinger theorem relates Fermi surface volume to electron density per spin . It holds in an arbitrary Fermi liquid but is widely believed to break when a fermionic self-energy…
Non-BCS Pairing by a Singular Dynamical Interaction
Artem G. Abanov, Andrey V. Chubukov
This review examines the theory of superconductivity in systems with {\em singular dynamical} electron-electron interaction and contrasts it with a conventional BCS superconductivi…
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…
Kinetics of Bose-Einstein condensation of magnons in Yttrium Iron Garnet films
Hulin Yang, Gang Li, Haichen Jia +2
In this article, we explain the reason of the apparent contradiction between recent experiments [1] and [2] and earlier theoretical predictions [3] of strongly asymmetric condensat…
Superconductivity Near a Quantum Critical Point: Bounds on the Transition Temperature in the -Model
Ahmed Elezaby, Artem Abanov
Near a quantum critical point (QCP) in a metal, strong Fermion-Fermion interactions mediated by soft collective bosons give rise to two competing phenomena: non-Fermi liquid behavi…
