Subgap two-particle spectral weight in disordered $s$-wave superconductors: Insights from mode coupling approach

Prathyush P. Poduval, Abhisek Samanta, Prashant Gupta +2

We study the two-particle spectral functions and collective modes of weakly disordered superconductors using a disordered attractive Hubbard model on square lattice. We show that t…
