de Broglie-Proca and Bopp-Podolsky massive photon gases in cosmology
(Iop Publishing Ltd, 2017-04-01)
We investigate the influence of massive photons on the evolution of the expanding universe. Two particular models for generalized electrodynamics are considered, namely de BroglieProca and Bopp-Podolsky electrodynamics. ...

Gravitation: In search of the missing torsion
(2007-12-01)
A linear Lorentz connection has always two fundamental derived characteristics: curvature and torsion. The latter is assumed to vanish in general relativity. Three gravitational models involving non-vanishing torsion are ...

Tsallis’ maximum entropy ansatz leading to exact analytical time dependent wave packet solutions of a nonlinear Schrödinger equation
(Elsevier, 2013-02)
Tsallis maximum entropy distributions provide useful tools for the study of a wide range of scenarios in mathematics, physics, and other fields. Here we apply a Tsallis maximum entropy ansatz, the q-Gaussian, to obtain ...
