Non-Magnetic Impurity induced in-gap bound states in two band superconductors
T. K. Ng, Y. Avishai
In this paper we study the effect of single non-magnetic impurity in two-band s-wave superconductors where the two s-wave order parameters have relative phase between them…

The one-dimensional Coulomb Problem
G. Abramovici, Y. Avishai
One-dimensional scattering by a Coulomb potential V(x)=lambda/|x| is studied for both repulsive (c>0) and attractive (c<0) cases. Two methods of regularizing the singularity at x=0…
