RODRIGUEZ-DUENAS, Ferney Javier. Optical and transport properties of cuasi-one dimensional electronic systems. Rev. acad. colomb. cienc. exact. fis. nat. [online]. 2018, vol.42, n.163, pp.150-161. ISSN 0370-3908.  https://doi.org/10.18257/raccefyn.482.

In this paper we study the optical and transport properties of interactive electron systems both with external potentials and between them. In the first part, we analyze the electronic properties of quasi-unidimensional systems under different types of disorder for an electron interacting with a finite number of localized potentials. In the second part, the results of the photoemission properties for a highly correlated many-body system, where electrons interact strongly with each other, show the presence of a Fermi-edge singularity. In both cases, we used and demonstrated the method of Green’s functions as the effective theory to obtain results comparable to the experiments.
