W. Xu et al., GINZBURG-LANDAU EQUATIONS FOR A D-WAVE SUPERCONDUCTOR WITH NONMAGNETIC IMPURITIES, Physical review. B, Condensed matter, 53(18), 1996, pp. 12481-12495
The Ginzburg-Landau equations for a d-wave superconductor with nonmagn
etic impurities are derived in the framework of the Gor'kov's weak-cou
pling theory of superconductivity. The weak scattering in the Born lim
it as well as the strong scattering in the unitary limit of the impuri
ties are both considered in the calculation. The effect of impurities
on the magnetic field penetration depth and the induced s-wave order p
arameter are also studied.
