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…
Pair-Density-Wave Order and Paired Fractional Quantum Hall Fluids
Luiz H. Santos, Yuxuan Wang, Eduardo Fradkin
The properties of the isotropic incompressible fractional quantum Hall (FQH) state are described by a paired state of composite fermions in zero (effective) magnetic field,…
Weak-Pairing Higher Order Topological Superconductors
Yuxuan Wang, Mao Lin, Taylor L. Hughes
Conventional topological superconductors are fully gapped in the bulk but host gapless Majorana modes on their boundaries. We instead focus on a new class of superconductors, secon…
Pair Density Waves in Superconducting Vortex Halos
Yuxuan Wang, Stephen D. Edkins, Mohammad H. Hamidian +3
We analyze the interplay between a d-wave uniform superconducting and a pair-density-wave (PDW) order parameter in the neighborhood of a vortex. We develop a phenomenological nonli…
