Effects of neutrino oscillations on the supernova signal in LVD
M. Aglietta, P. Antonioli, G. Bari +21
We study the impact of neutrino oscillations on the supernova neutrino signal in the Large Volume Detector (LVD). The number of expected events for a galactic supernova (D=10 kpc)…
A proposal of quantum logic gates using cold trapped ions in a cavity
F. L. Semiao, A. Vidiella-Barranco, J. A. Roversi
We propose a scheme for implementation of logical gates in a trapped ion inside a high-Q cavity. The ion is simultaneously interacting with a (classical) laser field as well as wit…
Status of a hybrid three-neutrino interpretation of neutrino data
M. M. Guzzo, P. C. de Holanda, M. Maltoni +3
We reanalyze the non-standard interaction (NSI) solutions to the solar neutrino problem in the light of the latest solar, atmospheric and reactor neutrino data. We show that such s…
Global Analysis of the post-SNO Solar Neutrino Data for Standard and Non-Standard Oscillation Mechanisms
A. M. Gago, M. M. Guzzo, P. C. de Holanda +4
What can we learn from solar neutrino observations? Is there any solution to the solar neutrino anomaly which is favored by the present experimental panorama? After SNO results, is…
CERN to Gran Sasso; An ideal distance for superbeam?
Hisakazu Minakata, Hiroshi Nunokawa
We use the CP trajectory diagram as a tool for pictorial representation of the genuine CP and the matter effects to explore the possibility of an in situ simultaneous measurement o…
CP Trajectory Diagram; A tool for pictorial representation of CP and matter effects in neutrino oscillations
Hisakazu Minakata, Hiroshi Nunokawa
We introduce "CP trajectory diagram in bi-probability space" as a powerful tool for pictorial representation of the genuine CP and the matter effects in neutrino oscillations. Exis…
Quaternionic potentials in non-relativistic quantum mechanics
S. De Leo, C. G. Ducati, Celso C. Nishi
We discuss the Schrodinger equation in presence of quaternionic potentials. The study is performed analytically as long as it proves possible, when not, we resort to numerical calc…
Quantum open systems and turbulence
L. F. Santos, C. O. Escobar
We show that the problem of non conservation of energy found in the spontaneous localization model developed by Ghirardi, Rimini and Weber is very similar to the inconsistency betw…
Columnar defects acting as passive internal field detectors
A. V. Silhanek, L. Civale, M. A. Avila
We have studied the angular dependence of the irreversible magnetization of several YBaCuO and 2H-NbSe single crystals with columnar defects tilted off the c-axis.…
Theory and experiment of the ESR of Co in Zn % (OH)PO and Mg(OH)AsO
M. E. Foglio, M. C dos Santos, G. E. Barberis +4
Experiments of Electron Spin Resonance (ESR) were performed on Co substituting Zn or Mg in powder samples of Zn(OH)PO and Mg(OH)AsO. The obse…
Renormalization approach for quantum-dot structures under strong alternating fields
P. A. Schulz, P. H. Rivera, Nelson Studart
We develop a renormalization method for calculating the electronic structure of single and double quantum dots under intense ac fields. The nanostructures are emulated by lattice m…
Thermodynamic potential of the Periodic Anderson Model with the X-boson method: Chain Approximation
R. Franco, M. S. Figueira, M. E. Foglio
The Periodic Anderson Model (PAM) in the limit has been studied in a previous work employing the cumulant expansion with the hybridization as perturbation (M. S. Figue…
Effects of an electron gas on the negative trion in semiconductor quantum wells
Luis C. O. Dacal, Jose A. Brum
We present here the results of calculations of the negative trion binding energy in the presence of an electron gas. The screening of the Coulomb interaction and the Pauli exclusio…
Binding energy of negatively charged exciton in a semiconductor quantum well: the role of interface defects
Luis C. O. Dacal, R. Ferreira, G. Bastard +1
We present a model to take into account the interface defects contribution on the binding energy of charged exciton in GaAs/AlGaAs quantum wells. The dependence of…
Qualitative understanding of the sign of t' asymmetry in the extended t-J Model and relevance for pairing properties
G. B. Martins, J. C. Xavier, L. Arrachea +1
Numerical calculations illustrate the effect of the sign of the next nearest-neighbor hopping term t' on the 2-hole properties of the t-t'-J model. Working mainly on 2-leg ladders,…
X-boson cumulant approach to the periodic Anderson model
R. Franco, M. S. Figueira, M. E. Foglio
The Periodic Anderson Model (PAM) can be studied in the infinite U limit by employing the Hubbard X operators to project out the unwanted states. We have already studied this probl…
New localized Superluminal solutions to the wave equations with finite total energies and arbitrary frequencies
Michel Zamboni-Rached, Erasmo Recami, Hugo E. Harnandez-Figueroa
By a generalized bidirectional decomposition method, we obtain many new Superluminal localized solutions to the wave equation (for the electromagnetic case, in particular) which ar…
Timelapse
S. De Leo, P. Rotelli
We discuss the existence in an arbitrary frame of a finite time for the transformation of an initial quantum state into another e.g. in a decay. This leads to the introduction of a…

A. H. Campos, L. L. Lengruber, H. C. Reis +2
Top-down models for the origin of ultra high energy cosmic rays (UHECR's) propose that these events are the decay products of relic superheavy metastable particles, usually called…
