Ballistic Localization in Quasi-1D Waveguides with Rough Surfaces

Structure of eigenstates in a periodic quasi-1D waveguide with a rough surface is studied both analytically and numerically. We have found a large number of "regular" eigenstates for any high energy. They result in a very slow convergence to the classical limit in which the eigenstates are expected to be completely ergodic. As a consequence, localization properties of eigenstates originated from unperturbed transverse channels with low indexes, are strongly localized (delocalized) in the momentum (coordinate) representation. These eigenstates were found to have a quite unexpeted form that manifests a kind of "repulsion" from the rough surface. Our results indicate that standard statistical approaches for ballistic localization in such waveguides seem to be unappropriate.Comment: 5 pages, 4 figure

Positive Representations of L1 of a Vector Measure

We characterize the vector measures n on a Banach lattice such that the map |·|dn provides a quasi-norm which is equivalent to the canonical norm · n of the space L1(n) of integrable functions as an specific type of transformations of positive vector measures that we call cone-open transformations. We also prove that a vector measure m on a Banach space X constructed as a cone-open transformation of a positive vector measure can be considered in some sense as a positive vector measure by defining a new order on X.Ministerio de Educación y Ciencia MTM2006-11690-C0

A clear signature of the breakup modes for 9Be on a proton target at 5.6 MeV/nucleon

The breakup of 9Be is studied via an inelastic scattering experiment on a proton target at 5.6 A MeV in inverse kinematics. Two of the three cluster constituents (α and α) as well as the proton target recoil were recorded in a triple coincidence mode allowing a full kinematics approach analysis. In this respect relative α - α and α - n, Q-value and 9Be excitation spectra, energy spectra for all fragments as well as the energy spectrum of the recoil proton were reconstructed. A clear signature of the two breakup sequential modes (5He + 4He and 8Be + n) was identified via the recoiling proton reconstructed spectra together with the direct breakup decay. A strong 5He + 4He mode was observed compatible with previous beta decay experiments

La crisis migratoria de 2020 en las Islas Canarias: algunas opciones de solidaridad europea

The migratory crisis in the Canary Islands, as a consequence of the covid-19 pandemic and its socio-economic impact, as well as an unprecedented diplomatic crisis between Spain and Morocco, have demonstrated our country’s inability to cope on its own with the massive arrival of immigrants at its external borders. Considering that the response to this phenomenon cannot be solely national but supranational, it is worth identifying some solidarity mechanisms in the EU context that could have been applied to the case of the Canary Islands, especially in the area of temporary protection of migrants and the civil protection mechanism.La crisis migratoria en las islas Canarias, como consecuencia de la pandemia de COVD-19 y su impacto socioeconómico, así como una crisis diplomática entre España y Marruecos sin precedentes, han demostrado la incapacidad de nuestro país para hacer frente por sí sola a la llegada masiva de inmigrantes a sus fronteras exteriores. Considerando que la respuesta ante este fenómeno no puede ser únicamente nacional sino supranacional, conviene determinar algunos mecanismos de solidaridad en el contexto de la UE que pudieran haber sido aplicados al caso canario, especialmente en el ámbito de la protección temporal de los inmigrantes y el mecanismo de protección civil.  

Encuentros y desencuentros hispano-británicos en las aguas en torno a Gibraltar: ¿son posibles acuerdos de cooperación práctica?

El contencioso entre España y Reino Unido por la soberanía de Gibraltar y la jurisdicción de las aguas, se ha visto agravado en los últimos años por el incremento de incidentes entre sus Cuerpos y Fuerzas de Seguridad. Dichos incidentes se han convertido en una manifestación política de las discrepancias estatales sobre la titularidad de las zonas marítimas. Es por ello que se requiere buscar fórmulas para conseguir adoptar protocolos de actuación conjunta, respetando las posiciones nacionales sobre reclamación de soberanía, y con la finalidad de lograr hacer frente a los tráficos ilegales en la zona del Estrecho de Gibraltar
