Quantum geometric localization length and localization criticality in an ideally flat Chern band
Xu-Cheng Wang, Yang Qi
We propose that the localization length in an isolated, ideally flat Chern band is set by quantum geometry. We explore the corresponding localization transition and its critical sc…
Emergent magnetic pseudogap from phase fluctuations and hierarchy of scales in two-dimensional superconductors
Xu-Cheng Wang, Yang Qi
Preformed pairs and phase fluctuations are believed to play a vital role in predicting the charge pseudogap in the normal state of two-dimensional superconductors. In this work, we…
The interplay of phase fluctuations and nodal quasiparticles: ubiquitous Fermi arcs in two-dimensional d-wave superconductors
Xu-Cheng Wang, Xiao Yan Xu, Yang Qi
We propose that the pseudogap and Fermi arcs can universally emerge due to thermal (static) phase fluctuations in the normal state of 2D nodal superconductors. By considering a min…
Phase fluctuations in two-dimensional superconductors and pseudogap phenomenon
Xu-Cheng Wang, Yang Qi
We study the phase fluctuations in the normal state of generic two-dimensional superconducting systems with s-wave pairing. The effect of phase fluctuations of the pairing fields c…
