Post-colonial legacies in Seville: traces of the Ibero-American Exhibition, 1929
The Ibero-American Exhibition (IAE), celebrated in Seville in 1929, has endured and survived a number of periods which have affected not only its use, but also its meaning. The aim of this paper is to evaluate the context in which the IAE was designed, highlighting connections with broader international understandings: first, regarding the creation of new identities during the Spanish post-colonial period (in both Latin America and Spain); second, the organisation of international exhibitions, which aimed at showcasing advances (technological and colonial), as well as the construction of colonial identities. These two conditions have a clear impact in the construction and delivery of the IAE project, which can be traced on the legacy that the Ibero-American Exhibition has had in Seville, especially through its pavilions, built as permanent structures. The built environment in Seville will serve to evaluate how it was used in the past, in the present, and how it could become a future environment for a further understanding of the relationships between Spain and its former colonies in Latin America
Dressed tunneling approximation for electronic transport through molecular transistors
A theoretical approach for the non-equilibrium transport properties of
nanoscale systems coupled to metallic electrodes with strong electron-phonon
interactions is presented. It consists in a resummation of the dominant Feynman
diagrams from the perturbative expansion in the coupling to the leads. We show
that this scheme eliminates the main pathologies found in previous simple
analytical approaches for the polaronic regime. The results for the spectral
and transport properties are compared with those from several other approaches
for a wide range of parameters. The method can be formulated in a simple way to
obtain the full counting statistics. Results for the shot and thermal noise are
presented.Comment: 11 pages, 11 figures. Accepted for publication in Physical Review
