Analysis of the XENON100 dark matter search data
Aprile, E.; Alfonsi, M.; Arisaka, K.; Arneodo, F.; Balan, C.; Baudis, L.; Behrens, A.; Beltrame, P.; Bokeloh, K.; Brown, E.; Bruno, G.; Budnik, R.The XENON100 experiment, situated in the Laboratori Nazionali del Gran Sasso, aims at the direct detection of dark matter in the form of weakly interacting massive particles (WIMPs), based on their interactions with xenon nuclei in an ultra low background dual-phase time projection chamber. This paper describes the general methods developed for the analysis of the XENON100 data. These methods have been used in ...
Superconducting properties of MgB2 from first principles
Floris, A.; Sanna, A.; Lüders, M.; Profeta, G.; Lathiotakis, N. N.; Marques, M. A. L.; Franchini, C.; Gross, E. K. U.; Continenza, A.; Massidda, S.The discovery of superconductivity in MgB2, with a rather high transition temperature, has triggered a large number of theoretical and experimental investigations on important issues such as, e.g., the role of gap anisotropy over the Fermi surface (multi-gap superconductivity). We report here the results obtained in this compound using the density functional theory for superconductors, recently proposed by the ...
Octopus: a tool for the application of time-dependent density functional theory
Castro, Alberto; Appel, Heiko; Oliveira, Micael; Rozzi, Carlo A.; Andrade, Xavier; Lorenzen, Florian; Marques, M. A. L.; Gross, E. K. U.; Rubio, AngelWe report on the background, current status, and current lines of development of the octopus project. This program materializes the main equations of density-functional theory in the ground state, and of time-dependent density-functional theory for dynamical effects. The focus is nowadays placed on the optical (i.e. electronic) linear response properties of nanostructures and biomolecules, and on the non-linear...
Nodulação e micorrização em Anadenanthera peregrina var. falcata em solo de cer...
Gross,E.; Cordeiro,L.; Caetano,F. H.Anadenanthera peregrina var. falcata (angico-do-cerrado), uma leguminosa arbórea, forma associações simbióticas com bactérias fixadoras de nitrogênio (rizóbios) e com fungos micorrízicos arbusculares. Com o objetivo de avaliar a eficiência da inoculação de fungos micorrízicos e rizóbios no crescimento inicial de plantas de angico-do-cerrado, crescidas em solo autoclavado e em solo não autoclavado com e sem inoc...
