Disorder and superfluid density in overdoped cuprate superconductors
Disorder and superfluid density in overdoped cuprate superconductors
One of the hallmarks of clean, $d$-wave superconductivity is a linear temperature dependence of superfluid density in the low-temperature limit. Here, the authors show that weak scattering, combined with a realistic model of the cuprate Fermi surface, allows the linear behavior of superfluid density to persist in the presence of …
