Mixing of superconducting $d_{x^2-y^2}$ state with s-wave states for different filling and temperature

Angsula Ghosh, Sadhan K. Adhikari

We study the order parameter for mixed-symmetry states involving a major $d_{x^2-y^2}$ state and various minor s-wave states ($s$, $s_{xy}$, and $s_{x^2+y^2}$) for different fillin…
