摘要：

Using a combination of quantum Monte Carlo simulation, perturbation theory, and maximum-entropy analytic continuation, we calculate the density of states for a dilute-magnetic-alloy superconductor. We find that the peak location of the gap states moves more quickly with increasing Kondo temperature than predicted by Zittartz et al., and that the integrated intensity of the gap states is in extreme qualitative disagreement with that prediction. © 1990 The American Physical Society.
