Low-lying excitations induced by non-magnetic impurities in -wave superconductors

Nakai, Noriyuki; Nagai, Yuki ; Machida, Masahiko

We have performed numerical calculations for low-lying excitations induced by a single non-magnetic impurity in a -wave superconductor on the basis of two different frameworks. One is the Bogoliubov-de Gennes theory in real coordinates, while the other is the Born approximation in wave-number coordinates. This paper shows that these results for low-lying excitations are identical by using Fourier transformations.
