Probing nonlocal superconducting fluctuations with covariance noise magnetometry
Gustav Romare, Ilya Esterlis, Shimon Kolkowitz +1
The nonlocal superconducting fluctuation corrections to the conductivity tensor are calculated within the time-dependent Ginzburg-Landau framework, and their…
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 an adiabatic limit a Fermi liquid state of an electron-phonon system described by Migdal-Eliashberg theory remains stable before a dressed phonon soft…
Superconductivity near two-dimensional Van Hove singularities: a determinant quantum Monte Carlo study
Gustav Romare, Daniel Shaffer, Alex Levchenko +2
The superconducting transition temperature of the two-dimensional attractive Hubbard model is computed in the vicinity of both ordinary (logarithmic) and higher-order (power-…
