Double Diffraction White Light Imaging: First Results with Bidimensional Diffraction
Jose J Lunazzi, Noemi I Rodriguez Rivera
The double diffraction of white light can produce a thin-prism-like image in certain conditions by using ordinary diffraction gratings. The diffractive deviation of rays happens ma…
Modelling dynamics of samples exposed to free-electron-laser radiation with Boltzmann equations
Beata Ziaja, Antonio R. B. de Castro, Edgar Weckert +1
We apply Boltzmann equations for modelling the radiation damage in samples irradiated by photons from free electron laser (FEL). We test this method in a study case of a sphericall…
Effective cross-Kerr nonlinearity and robust phase gates with trapped ions
F. L. Semiao, A. Vidiella-Barranco
We derive an effective Hamiltonian that describes a cross-Kerr type interaction in a system involving a two-level trapped ion coupled to the quantized field inside a cavity. We ass…
Orientational Defects in Ice Ih: An Interpretation of Electrical Conductivity Measurements
Maurice de Koning, Alex Antonelli, Antonio J. R. da Silva +1
We present a first-principles study of the structure and energetics of Bjerrum defects in ice Ih and compare the results to experimental electrical conductivity data. While the DFT…
First Observations of Separated Atmospheric Muon Neutrino and Muon Anti-Neutrino Events in the MINOS Detector
MINOS Collaboration
The complete 5.4 kton MINOS far detector has been taking data since the beginning of August 2003 at a depth of 2070 meters water-equivalent in the Soudan mine, Minnesota. This pape…
Theory of Neutrinos: A White Paper
R. N. Mohapatra, S. Antusch, K. S. Babu +29
During 2004, four divisions of the American Physical Society commissioned a study of neutrino physics to take stock of where the field is at the moment and where it is going in the…
The Einstein-Hilbert Lagrangian Density in a 2-dimensional Spacetime is an Exact Differential
Roldao da Rocha, W. A. Rodrigues
Recently Kiriushcheva and Kuzmin claimed to have shown that the Einstein-Hilbert Lagrangian cannot be written in any coordinate gauge as an exact differential in a 2-dimensional sp…
Derivative dispersion relations above the physical threshold
R. F. Avila, M. J. Menon
We discuss some formal and practical aspects related to the replacement of Integral Dispersion Relations (IDR) by derivative forms, without high-energy approximations. We first dem…
Angra Neutrino Project: status and plans
J. C. Anjos, A. F. Barbosa, R. Z. Funchal +6
We present the status and plans of the Angra Project, a new nuclear reactor neutrino oscillation experiment, proposed to be built in Brazil at the Angra dos Reis nuclear reactor co…
Noether Symmetries and Critical Exponents
Yuri Bozhkov
We show that all Lie point symmetries of various classes of nonlinear differential equations involving critical nonlinearities are variational/divergence symmetries.
Thermodynamic modeling of phase separation in manganites
J. Sacanell, F. Parisi, J. C. P. Campoy +1
We present a phenomenological model based on the thermodynamics of the phase separated state of manganites, accounting for its static and dynamic properties. Through calorimetric m…
Variation in the luminosity of Kerr quasars due to extra dimension in brane Randall-Sundrum model
Roldao da Rocha, Carlos H. Coimbra-Araujo
We propose an alternative theoretical approach showing how the existence of an extra dimension in Randall-Sundrum model can estimate the correction in the horizon of Schwarzschild…
Efficient evaluation of decoherence rates in complex Josephson circuits
David P. DiVincenzo, Frederico Brito, Roger H. Koch
A complete analysis of the decoherence properties of a Josephson junction qubit is presented. The qubit is of the flux type and consists of two large loops forming a gradiometer an…
Introduction to Quantum Cryptography
Gustavo Rigolin, Andres A. Rieznik
We show in details the four quantum key distribution protocols which initiated the important field of quantum cryptography, using an accessible language for undergraduate students.…
Generalized Teleportation Protocol
Goren Gordon, Gustavo Rigolin
A generalized teleportation protocol (GTP) for N qubits is presented, where the teleportation channels are non-maximally entangled and all the free parameters of the protocol are c…
Variational approach to dequantization
Ricardo A. Mosna, Ian P. Hamilton, Luigi Delle Site
We present a dequantization procedure based on a variational approach whereby quantum fluctuations latent in the quantum momentum are suppressed. This is done by adding generic loc…
Singular solutions to the Seiberg-Witten and Freund equations on flat space from an iterative method
Ricardo A. Mosna
Although it is well known that the Seiberg-Witten equations do not admit nontrivial solutions in flat space, singular solutions to them have been previously exhibited -- eith…
Complex Hyperbolic Structures on Disc Bundles over Surfaces
Sasha Anan'in, Carlos H. Grossi, Nikolay Gusevskii
We study complex hyperbolic disc bundles over closed orientable surfaces that arise from discrete and faithful representations H_n->PU(2,1), where H_n is the fundamental group of t…

Marcelo Ventura Freire, Serguei Popov, Marina Vachkovskaia
Let be the set of points (we call the elements of centers) of Poisson process in , , with unit intensity. Consider the allocation of to which is s…
Dynamics of chiral oscillations - A comparative analysis with spin-flipping
Alex E. Bernardini
Chiral oscillation as well as spin flipping effects correspond to quantum phenomena of fundamental importance in the context of particle physics and, in particular, of neutrino phy…
