The Surface Detector System of the Pierre Auger Observatory
I. Allekotte, A. F. Barbosa, P. Bauleo +17
The Pierre Auger Observatory is designed to study cosmic rays with energies greater than 10^{19} eV. Two sites are envisaged for the observatory, one in each hemisphere, for comple…
A second look at N=1 supersymmetric AdS_4 vacua of type IIA supergravity
Gerardo Aldazabal, Anamaria Font
We show that a class of type IIA vacua recently found within the N=4 effective approach corresponds to compactification on Ads_4 \times S^3 \times S^3/Z_2^3. The results obtained u…
Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei
The Pierre Auger Collaboration
Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the highest energies, which are correlated with the…
Poisson-Lie T-Duality and non trivial monodromies
A. Cabrera, H. Montani, M. Zuccalli
We describe a general framework for studying duality between different phase spaces which share the same symmetry group . Solutions corresponding to collective dynamics…
Upper limit on the diffuse flux of UHE tau neutrinos from the Pierre Auger Observatory
The Pierre Auger Collaboration
The surface detector array of the Pierre Auger Observatory is sensitive to Earth-skimming tau-neutrinos that interact in the Earth's crust. Tau leptons from charged-cur…
Casimir effect in 2+1 dimensional noncommutative theories
C. D. Fosco, G. A. Moreno
We study the Dirichlet Casimir effect for a complex scalar field on two noncommutative spatial coordinates plus a commutative time. To that end, we introduce Dirichlet-like boundar…
One-loop effects in a self-dual planar noncommutative theory
C. D. Fosco, G. A. Moreno
We study the UV properties, and derive the explicit form of the one-loop effective action, for a noncommutative complex scalar field theory in 2+1 dimensions with a Grosse-Wulkenha…
The effect of the topology on the spatial ultimatum game
M. N. Kuperman, S. Risau Gusman
In this work we present an analysis of a spatially non homogeneous ultimatum game. By considering different underlying topologies as substrates on top of which the game takes place…
Analytical approach to bit-string models of language evolution
Damian H. Zanette
A formulation of bit-string models of language evolution, based on differential equations for the population speaking each language, is introduced and preliminarily studied. Connec…
Synchronization of phase oscillators with heterogeneous coupling: A solvable case
Gabriel H. Paissan, Damian H. Zanette
We consider an extension of Kuramoto's model of coupled phase oscillators where oscillator pairs interact with different strengths. When the coupling coefficient of each pair can b…
Electronic Transport through Magnetic Molecules with Soft Vibrating Modes
P. S. Cornaglia, Gonzalo Usaj, C. A. Balseiro
The low-temperature transport properties of a molecule are studied in the field-effect transitor geometry. The molecule has an internal mechanical mode that modulates its electroni…
Global firing induced by network disorder in ensembles of active rotators
Claudio J. Tessone, Damián H. Zanette, Raúl Toral
We study the influence of repulsive interactions on an ensemble of coupled excitable rotators. We find that a moderate fraction of repulsive interactions can trigger global firing…
Comment on: ``Zero temperature conductance of parallel T-shape double quantum dots'' [Physica E 39 (2007) 214, arXiv:0708.1842v1]
P. S. Cornaglia
In a recent paper [Physica E 39 (2007) 214, arXiv:0708.1842v1] Crisan, Grosu and Tifrea revisited the problem of the conductance through a double quantum dot molecule connected to…
Spectral density of an interacting dot coupled indirectly to conducting leads
L. Vaugier, A. A. Aligia, A. M. Lobos
We study the spectral density of electrons rho in an interacting quantum dot (QD) with a hybridization lambda to a non-interacting QD, which in turn is coupled to a non-interacting…
Demographic growth and the distribution of language sizes
Damian H. Zanette
It is argued that the present log-normal distribution of language sizes is, to a large extent, a consequence of demographic dynamics within the population of speakers of each langu…
Noncommutative real scalar field theory in 2+1 dimensions at finite temperature
C. D. Fosco, G. A. Silva
We study thermal effects for a noncommutative real scalar field in 2+1 dimensions including a Grosse-Wulkenhaar term. Using a perturbative expansion for the free energy, we deduce…
Effects of interactions in transport through Aharonov-Bohm-Casher interferometers
A. M. Lobos, A. A. Aligia
We study the conductance through a ring described by the Hubbard model (such as an array of quantum dots), threaded by a magnetic flux and subject to Rashba spin-orbit coupling (SO…
How to become a superhero
P. M. Gleiser
We analyze a collaboration network based on the Marvel Universe comic books. First, we consider the system as a binary network, where two characters are connected if they appear in…
Magnetic State Modification Induced by Superconducting Response in Ferromagnet/Superconductor Hybrids
C. Monton, F. de la Cruz, J. Guimpel
Magnetization measurements in superconductor/ferromagnet Nb/Co superlattices show a complex behavior as a function of temperature, applied field and sample history. In base to a si…
A mechanism for unipolar resistance switching in oxide non-volatile memory devices
M. J. Sanchez, M. J. Rozenberg, I. H. Inoue
Building on a recently introduced model for non-volatile resistive switching, we propose a mechanism for unipolar resistance switching in metal-insulator-metal sandwich structures.…
Multifloquet to single electronic channel transition in the transport properties of a resistive 1D driven disordered ring
F. Foieri, L. Arrachea, M. J. Sanchez
We investigate the dc response of a 1D disordered ring coupled to a reservoir and driven by a magnetic flux with a linear dependence on time. We identify two regimes: (i) A localiz…
