The special role of the first Matsubara frequency for superconductivity near a quantum-critical point -- the non-linear gap equation below and spectral properties in real frequencies
Yi-Ming Wu, Artem Abanov, Yuxuan Wang +1
Near a quantum-critical point in a metal a strong fermion-fermion interaction, mediated by a soft boson, destroys fermionic coherence and also gives rise to superconductivity. In a…
Superconductivity above a quantum critical point in a metal -- gap closing vs gap filling, Fermi arcs, and pseudogap behavior
Artem Abanov, Yi-Ming Wu, Yuxuan Wang +1
We consider a quantum-critical metal with interaction mediated by fluctuations of a critical order parameter. This interaction gives rise to two competing tendencies -- pairing and…
Multiple pairing states and temperature-dependent gap anisotropy for superconductivity near a nematic quantum-critical point
Avraham Klein, Yi-Ming Wu, Andrey Chubukov
Superconductivity in many strongly correlated materials appears in proximity to a density-wave or nematic order and is believed to be mediated by quantum-critical (QC) fluctuations…
Pairing in quantum-critical systems: , , and their ratio
Yi-Ming Wu, Artem Abanov, Andrey V. Chubukov
We compute the ratio of the pairing gap at and for a set of quantum-critical models in which the pairing interaction is mediated by a gapless boson with local susce…
The Conditions for Pomeranchuk Instability in a Fermi Liquid
Yi-Ming Wu, Avraham Klein, Andrey V. Chubukov
We perform a microscropic analysis of how the constraints imposed by conservation laws affect Pomeranchuk instabilities in a Fermi liquid. The conventional view is that these…
