The reflection spectra of the Bechgaard salts:a theoretical determination

Abstract

The aim of this contribution is to analyze to some extent the reflectivity of the family of organic salts known as the Bechgaard salts. The reflectivity will be calculated using a well known theoretical framework,and results for the electrical conductivity and susceptibility of these materials. The result obtained for the reflectivity is a non-linear expression depending on various material parameters within the Hubbard model. The position of the region where the reflectivity tends to zero will also be determined as a function of model parameters. A possibility of extending the results to 2D systems is briefly mentioned.
