Positron annihilation spectroscopy techniques applied to the study of an HPGe detector.
(São Sebastião, 2012-09-02)
Doppler Broadening Spectroscopy of the large Ge crystal of an HPGe detector was
perforrned using positrons from pair production of 6.13 MeV ϒ-rays from the 19F(p,αϒ) 16O reaction. Two HPGe detectors facing opposite sides ...
Interferometria quântica com cavidades
(Universidade Federal de Minas GeraisUFMG, 2006-05-26)
Using type I parametric down conversion, coincidence detection and the Hong-Ou-Mandel interferometer modified with the introduction of a Fabry-Perot cavity in one of its arms, we map the temporal distribution of the photon ...

In this paper the southern cometary nebula GRV10 and its environment are investigated. The object is connected with a molecular cloud (its dimensions are ~4 pc). 12CO (1-0) observations toward GRV10 revealed the presence ...
Chiral-mediated entanglement in an Aharonov-Bohm ring
(American Physical Society, 2012-01)
We study the orbital entanglement in a biased Aharonov-Bohm ring connected in a four-terminal setup. We find that the concurrence achieves a maximum when the magnetic flux Φ B coincides with an integer number of a half ...
Birth Rates, Factor Shares, and Growth
(Universidad de los Andes, Facultad de Economía, CEDE, 2019)
Increases in capital shares affect the marginal productivity of capital, stimulating capital accumulation. Can a decrease in labor shares reduce the supply of labor? We explore this question using a model of fertility ...
