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…

Delay Update in determinant quantum Monte Carlo
Fanjie Sun, Xiao Yan Xu
Determinant quantum Monte Carlo (DQMC) is a widely used unbiased numerical method for simulating strongly correlated electron systems. However, the update process in DQMC is often…
