Moiré patterns in quantum images
J. A. O. Huguenin, M. P. Almeida, P. H. Souto Ribeiro +1
We observed moiré fringes in spatial quantum correlations between twin photons generated by parametric down-conversion. Spatially periodic structures were nonlocally superposed giv…
Quantum critical point in heavy fermions
Mucio Amado Continentino
The concept that heavy fermions are close to a quantum critical point and that this proximity determines their physical behavior, has opened new perspectives in the study of these…
The Thirring-Wess Model Revisited: A Functional Integral Approach
L. V. Belvedere, A. F. Rodrigues
We consider the Wess-Zumino-Witten theory to obtain the functional integral bosonization of the Thirring-Wess model with an arbitrary regularization parameter. Proceeding a systema…
Is there an enhancement of muons at sea level from transient events?
C. E. Navia, C. R. A. Augusto, M. B. Robba +2
In a recent study of a search for enhancements from the galactic center with muons at sea level using the TUPI muon telescope, we have found several ground level enhancements (GLEs…
General relativistic effects of strong magnetic fields on the gravitational force: a driving engine for bursts of gamma rays in SGRs?
Manuel Malheiro, Subharthi Ray, Herman J. M. Cuesta +1
In general relativity all forms of energy contribute to gravity and not only just ordinary matter as in Newtonian Physics. This fact can be seen in the modified hydrostatic equilib…
Statistical models of diffusion and aggregation for coke formation in a catalyst pore
Fabio D. A. Aarao Reis
We simulated models of diffusion and aggregation in long pores of small widths in order to represent the basic mechanisms of coke deposition in catalysts' pores. Coke precursors ar…
