Extended Drude model analysis of noble metals

We have applied the extended Drude model (EDM) to noble metals of Cu, Ag, and Au. Drude parameters are obtained self‐consistently without using the sum rule or any approximation. The core polarization contribution ε∞ is shown to be large due to shallow d‐orbitals. The frequency dependent mass enhanc...
