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 the…
Optical signatures of antiferromagnetic correlations in a strongly interacting quantum Hall MoSe2 monolayer
Jiho Sung, Pavel A. Volkov, Ilya Esterlis +9
Strong magnetic fields quench the kinetic energy of electrons, leading to the formation of flat energy bands, known as Landau levels (LLs). In this situation, even weak interaction…
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-…
Spin-triplet paired Wigner crystal stabilized by quantum geometry
Dmitry Zverevich, Alex Levchenko, Ilya Esterlis
We have used variational states to analyze the effects of band geometry on the two-dimensional Wigner crystal with one and two electrons per unit cell. At sufficiently low electron…
