Multiple scattering of charged particles in a free electron gas
(American Physical Society, 2006-12)
We study the influence of electron-scattering processes on the angular distributions of point particles moving through a free-electron gas. Previous calculations for slow ions are extended to all (nonrelativistic) velocities. ...
Conceptual problem for noncommutative inflation and the new approach for nonrelativistic inflationary equation of state
(American Physical SocietyCollege Park, 2013)
In a previous paper, we connected the phenomenological noncommutative inflation of Alexander, Brandenberger and Magueijo [ Phys. Rev. D 67 081301 (2003)] and Koh and Brandenberger [ J. Cosmol. Astropart Phys. 2007 21 ()] ...
Quantum scattering in one dimension
A self-contained discussion of non-relativistic quantum scattering is presented in the case of central potentials in one space dimension, which will facilitate the understanding of the more complex scattering theory in two ...
On the nonminimal vector coupling in the Duffin-Kemmer-Petiau theory and the confinement of massive bosons by a linear potential
(Iop Publishing Ltd, 2010-02-05)
The vector couplings in the Duffin-Kemmer-Petiau (DKP) theory have been revised. It is shown that minimal and nonminimal vector potentials behave differently under charge-conjugation and time-reversal transformations. In ...
Power counting and renormalization group invariance in the subtracted kernel method for the two-nucleon system

SYMMETRIES AND QUANTUM MECHANICS
Symmetries play a key role in investigation of the laws of Nature. Sometimes, unusual properties of a physical system indicate on the presence of a hidden symmetry. The analysis of the latter helps to understand better the ...
Eletrodinâmica de ordem superior em (2+1)D
(Universidade Estadual Paulista (UNESP), 2007-06-15)
We present in this work a number of results in Poldolsky's formulation of the (2+1) dimensional Electromagnetism. We focus our attention on the nonrelativistic regime of scatterings. We analyse the possibility of existence ...
Integrais de caminho na mecânica quântica e na teoria quântica de campos como base para as regras de Feynman
(Universidade Estadual Paulista (UNESP), 2016-10-21)
One of the alternative approaches used in quantum mechanics and quantum field theory, which takes the most advanced developments in the area, such as string theory, is to use the formalism of path-integrals . A path-integral ...
