Quantum Dynamics in Noisy Backgrounds: from sampling to dissipation and fluctuations
O. Oliveira, W. de Paula, T. Frederico +1
We investigate the dynamics of a quantum system coupled linearly to Gaussian white noise using functional methods. By performing the integration over the noisy field in the evoluti…
van der Waals and Casimir-Polder interactions between neutrons
James F. Babb, Mahir S. Hussein
We investigate the van der Waals interaction between neutrons using the theory of Casimir and Polder, wherein the potential for asymptotically large separations falls off as the in…
Two Dimensional Honeycomb Materials: random fields, dissipation and fluctuations
T. Frederico, O. Oliveira, W. de Paula +2
In this paper, we propose a method to describe the many-body problem of electrons in honeycomb materials via the introduction of random fields which are coupled to the electrons an…
Disappearance of Mott oscillations in sub-barrier elastic scattering of identical nuclei and atomic ions
M. S. Hussein, L. F. Canto, R. Donangelo +1
The scattering of identical nuclei at low energies exhibits conspicuous Mott oscillations which can be used to investigate the presence of components in the predominantly Coulomb i…
Unruh effect as foundation of universal gravitation within the cosmological scenario
Claudio Nassif, A. C. Amaro de Faria
We aim to build a simple model of a gas with temperature () in thermal equilibrium with a black-body that plays the role of the adiabatically expanding universe, so that each pa…
Theoretical study of the elastic breakup of weakly bound nuclei at near barrier energies
D. R. Otomar, P. R. S. Gomes, J. Lubian +2
We have performed CDCC calculations for collisions of Li projectiles on Co, Sm and Pb targets at near-barrier energies, to assess the importance of the…
A consistent four-body CDCC model of low-energy reactions: Application to 9Be + 208Pb
M. S. Hussein, P. Descouvemont, L. F. Canto
We investigate the Be + Pb elastic scattering, breakup and fusion at energies around the Coulomb barrier. The three processes are described simultaneously, with identic…
Fluctuation Phenomena in Chaotic Dirac Quantum Dots: Artificial Atoms on Graphene Flakes
J. G. G. S. Ramos, M. S. Hussein, A. L. R. Barbosa
We develop the stub model for the Dirac Quantum Dot, an electron confining device on a grapheme surface. Analytical results for the average conductance and the correlation function…
Current Status of Nuclear Physics Research
C. A. Bertulani, M. S. Hussein
In this review we discuss the current status of research in nuclear physics which is being carried out in different centers in the World. For this purpose we supply a short account…
Correlation functions and correlation widths in Quantum-Chaotic Scattering for mesoscopic systems and nuclei
J. G. G. S. Ramos, A. L. R. Barbosa, B. V. Carlson +2
We derive analytical expressions for the correlation functions of the electronic conductance fluctuations of an open quantum dot under several conditions. Both the variation of ene…
Geometrical parameter analysis of the high sensitivity fiber optic angular displacement sensor
João M. S. Sakamoto, Gefeson M. Pacheco, Cláudio Kitano +1
In this work, we present an analysis of the influence of the geometrical parameters on the sensitivity and linear range of the fiber optic angular displacement sensor, through comp…
