Optical response for a discrete stripe

In: Physica C: Superconductivity, 2004, vol. 408-410, p. 453-454

The optical response of a charge stripe in the presence of pinning impurities is investigated. We address the issue of a discrete description of the stripe, and discuss its quantitative relevance with respect to a continuum one in the light of recent optical-conductivity measurements in cuprate compounds.
