Density of States in Superconductor - Normal Metal - Superconductor Junctions
Abstract
We consider the chi0 dependence of the density of states inside the normal metal of a superconductor - normal metal - superconductor (SNS) junction.Here chi0 is the phase difference of two superconductors of the junction. It is shown that in the absence of electron-electron interaction the energy dependence of the density of states has a gap which decreases as chi0 increases and closes at chi0= pi. Both the analytical expressions for the chi0 dependence of the density of states and the results of numerical simulations are presented.
