Lithium Ionization by a Strong Laser Field

We study ab initio computations of the interaction of Lithium with a strong laser field. Numerical solutions of the time-dependent fully-correlated three-particle Schroedinger equation restricted to the one-dimensional soft-core approximation are presented. Our results show a clear transition from non-sequential to sequential double ionization for increasing intensities. Non sequential double ionization is found to be sensitive to the spin configuration of the ionized pair. This asymmetry, also found in experiments of photoionization of Li with synchrotron radiation, shows the evidence of the influence of the exclusion principle in the underlying rescattering mechanism

Guarding the border: watchtowers of the Nasrid Kingdom of Granada. Characterization and vulnerability assessment

RUIZ-JARAMILLO, J. y GARCÍA-PULIDO, L.J., 2018. Guarding the border: watchtowers of the Nasrid Kingdom of Granada. Characterization and vulnerability assessment. Heritage 2018: 6th International Conference on Heritage and Sustainable Development. Granada: Green Lines Institute for Sustainable Development, pp. 1511-1518The Islamic Nasrid kingdom of Granada occupied the mountainous areas of the south-eastern of the Iberian Peninsula. The frontier between the Nasrid kingdom and the Christian kingdom of Castile from 1232 to 1492 was controlled by an extensive network of watchtowers built by Nasrid through the provinces of Granada, Malaga, Almeria and the eastern parts of Jaen, Cordoba and Cadiz. They allowed controlling this frontier stablishing visual communication between them and the Nasrid centre at the Alhambra citadel. Even protected by Spanish Heritage law, many of these medieval towers and their cultural landscapes are in severe risk be-cause of anthropic action as well as natural deterioration. Within the framework of the R&D project called ‘Las atalayas que defendieron el reino nazarí de Granada. Análisis y docu-mentación científica (Nazalaya)”, the towers are being studied. As a complement of planimetry obtained by procedures as photogrammetry or terrestrial laser scanning (TLS), complete architectural surveys using non-destructive techniques are being performed as part of the analysis to obtain a global description of construction systems used.Universidad de Málaga.

Muslim heritage and environment: the case of the watchtowers of the nasrid kingdom of Granada (thirteenth to fifteenth century)

Editorial Universidad de Granada y Green Lines Institute for Sustainable Development, Granada, 2018. e-ISBN 978-84-338-6261-7This paper is devoted to the study of the different towers of the Nasrid kingdom of Granada (1232 to 1492) and their linked landscapes, as well as the evolution, preservation, resilience or transformation of their environment until present days. These late Islamic territories in medieval Iberia occupied the mountainous areas of the southeastern area of today’s Spain. There, a natural border was established between the Nasrid kingdom and the expansion of Castile during more than two centuries and a half. To control this frontier and establish visual communication between it and the Nasrid power centres lead by the Alhambra citadel, an extensive network of watchtowers and defensive towers linked to farmsteads was constructed. These towers are located in unique sites; being erected as reference landmarks of the territories on which they stand. These fortifications, with very diverse typology and morphology, are a faithful testimony to the different territorial structure that has taken place throughout history.Universidad de Málaga.

Exponential wealth distribution in a random market. A rigorous explanation

In simulations of some economic gas-like models, the asymptotic regime shows an exponential wealth distribution, independently of the initial wealth distribution given to the system. The appearance of this statistical equilibrium for this type of gas-like models is explained in a rigorous analytical way.Comment: 9 pages, 4 figure
