We investigate the effect of strong, nonmagnetic impurities on quasi-one-dimensional conventional and unconventional density waves (UDW). The conventional case remains unaffected similarly to s-wave superconductors in the presence of weak, nonmagnetic impurities. The thermodynamic properties of UDW were found to be identical to those of a d-wave superconductor in the unitary limit. The real and imaginary part of the optical conductivity is determined for electric fields applied in the…

It is argued that even if the impurity concentration is small, the quasiparticles in the superconducting state become strongly localized for a short coherence length d-wave superconductor, which leads to thermally activated behavior for the microwave conductivity and possibly for the London penetration depth.
