(AMER INST PHYSICS, 2011-01)Based on the one-body particle-antiparticle Dirac theory of electrons, a set of relativistic quantum fluid equations for a spin half plasma is derived. The particle-antiparticle nature of the relativistic particles is ...
-
(Amer Inst Physics, 2021)In the Madelung-Bohm approach to quantum mechanics, we consider a time dependent phase that depends quadratically on position, and we show that it leads to a Bohm potential that corresponds to a time dependent harmonic ...
-
(American Physical Society, 2016)We exhibit difficulties of different sorts which appear when using the Mathisson-Papapetrou equations, in particular in the description of highly relativistic particles presented in R. Plyatsko and M. Fenyk [Phys. Rev. D ...
-
(Universidad de Chile, 2025)We investigate the propagation of Alfvénic waves using linear kinetic theory, analysing the effects of plasma composition, finite temperature, and nonthermal velocity distributions. Our results demonstrate that both plasma ...
-
(Springer, 2021)It is showed that complex scalar fields with a self-interaction potential may propagate along null geodesics on isotropic flat Friedmann-Lemaitre-Robertson-Walker universes with different time-dependent scale factors. This ...

Line Shapes in Infrared Absorption by Solids and by Atomic or Molecular Species Embedded in Solids (AMER CHEMICAL SOC, 2010-07-15)When the target is in the solid state, most infrared spectral features are manifestly asymmetric; hence, a line shape function well-grounded in theory is necessary to ascertain the net energy taken by the associated ...
-
(Springer, 2021)It is proved that accelerating nondiffracting gravitational Airy wave-packets are solutions of linearized gravity. It is also showed that Airy functions are exact solutions to Einstein equations for non-accelerating ...
-
(American Institute of Physics, 2020)We present a phenomenological procedure of dealing with the COVID-19 (coronavirus disease 2019) data provided by government health agencies of 11 different countries. Usually, the exact or approximate solutions of ...

Spinning massive test particles in cosmological and general static spherically symmetric spacetimes (IOP Publishing, 2014)A Lagrangian formalism is used to study the motion of a spinning massive particle in Friedmann–Robertson–Walker and G¨odel spacetimes, as well as in a general Schwarzschild-like spacetime and in static spherically ...
-
(American Physical Society, 2015)The Einstein equations for an isotropic and homogeneous Friedmann-Robertson-Walker universe in the presence of a quintessence scalar field are shown to be described in a compact way, formally identical to the dynamics of ...
-
(IOP, 2022)A unification in terms of exact solutions for massless Klein-Gordon, Dirac, Maxwell, Rarita-Schwinger, Einstein, and bosonic and fermionic fields of any spin is presented. The method is based on writing all of the relevant ...
