Explaining the pseudogap through damping and antidamping on the Fermi surface by imaginary spin scattering

open access: yesCommunications Physics, 2022
The authors address a long-standing puzzle of pseudogap phenomenon observed in high temperature cuprates. Based on numerical calculations for the Hubbard model with analytic considerations, they find that a combination of strong-coupling ...
