Drude revisited

We generalize the Drude plasma frequency in terms of a tensor which we write in terms of integrals of the convective flux over the Fermi surface. We find an efficient computational scheme for its calculation and we apply it to noble metals under isotropic and anisotropic strain. The manuscript is in the arXiv:2011.04849. The paper was published in JOSAB.
