Direct observation of electronic inhomogeneities induced by point defect disorder in manganite films
M. Sirena, A. Zimmers, N. Haberkorn +7
We have investigated the influence of point defect disorder in the electronic properties of manganite films. Real-time mapping of ion irradiated samples conductivity was performed…
Universal scaling in transport out of equilibrium through a single quantum dot using the noncrossing approximation
P. Roura-Bas
The universal scaling behavior is studied for nonequilibrium transport through a quantum dot. To describe the dot we use the standard Anderson impurity model and use the non-equili…
Co-doped Ceria: Tendency towards ferromagnetism driven by oxygen vacancies
V. Ferrari, A. M. Llois, V. Vildosola
We perform an electronic structure study for cerium oxide homogeneously-doped with cobalt impurities, focusing on the role played by oxygen vacancies and structural relaxation. By…
Nonequilibrium dynamics of a singlet-triplet Anderson impurity near the quantum phase transition
P. Roura Bas, A. A. Aligia
We study the singlet-triplet Anderson model (STAM) in which a configuration with a doublet is hybridized with another with a singlet and a triplet, as a minimal model to describe t…
Atmospheric effects on extensive air showers observed with the Surface Detector of the Pierre Auger Observatory
The Pierre Auger Collaboration
Atmospheric parameters, such as pressure (P), temperature (T) and density, affect the development of extensive air showers initiated by energetic cosmic rays. We have studied the i…
Upper limit on the cosmic-ray photon fraction at EeV energies from the Pierre Auger Observatory
The Pierre Auger Collaboration, J. Abraham, P. Abreu +458
From direct observations of the longitudinal development of ultra-high energy air showers performed with the Pierre Auger Observatory, upper limits of 3.8%, 2.4%, 3.5% and 11.7% (a…
