    • In an experiment,15 there appears a cusp singularity in resistivity at Tc, which is much more pronounced than that in the present result in Fig. 4. One of the reasons for this discrepancy might be the use of a simplified parabolic DOS in this study, instead of a realistic one for the fcc tight-binding model.8
