Anisotropic optical conductivity of decagonal quasicrystals.

The optical conductivity of high quality decagonal quasicrystals of Ales Co&qCu&s and A162Co~5CupoSi3 shows a strong anisotropy between the periodic and the quasiperiodic directions. We suggest that this is due to the dramatic enhancement of scattering in the quasiperiodic planes. The analysis of the conductivity reveals a drastic difFerence between the electronic structure of the decagonal qua...

Optical Conductivity and Pseudo-Momentum Conservation in Anisotropic Fermi Liquids

Umklapp scattering determines the conductivity of clean metals. In typical quasi one-dimensional Fermi liquids with an open Fermi surface, certain pseudo-momenta do not decay by 2-particle collisions even in situations where Umklapp scattering relaxes the momentum of the quasi particles efficiently. Due to this approximate conservation of pseudo-momentum, a certain fraction of the electrical cu...

Out of plane optical conductivity in d-wave superconduc- tors

– We study theoretically the out of plane optical conductivity of d-wave superconductors in the presence of impurities at T = 0K. Unlike the usual approach, we assume that the interlayer quasi-particle transport is due to coherent tunneling. The present model describes the T 2 dependence of the out of plane superfluid density observed in Y BCO and T l2201 for example. In the optical conductivit...
