Disorder Induced Fluctuations of the Pairing Parameter in P-Wave Superconductors
G. Litak
We study the effect of site diagonal disorder on the pairing amplitude by a perturbation method. Using an extended Hubbard model with the intersite attraction we analyze fluctuatio…

Effect of Disorder on a D-wave Superconductor
Grzegorz Litak
We apply the Coherent Potential Approximation (CPA) to an extended Hubbard model to describe disordered superconductors with d-wave pairing. We discuss the pair-breaking effect cau…
