Lagrangian formalism for Rastall theory of gravity and Gödel-type universe
W. A. G. De Moraes, A. F. Santos
In the Rastall gravity a non-minimal coupling between geometry and matter fields is considered. Then the usual energy-momentum tensor conservation law is not valid. Here a Lagrangi…
Gödel and Gödel-type universes in K-essence theory
J. G. da Silva, A. F. Santos
In this paper, the Gödel-type solutions within the k-essence theory are investigated. The consistency of field equations, causality violation and existence of closed timelike curve…
Casimir effect and Stefan-Boltzmann law in Yang-Mills theory at finite temperature
A. F. Santos, Faqir C. Khanna
A non-Abelian gauge theory describes the strong interactions among particles with the commutator of generators are non-zero. An gauge theory describes the interactions that…
Non-abelian gauge symmetry for fields in phase space: a realization of the Seiberg-Witten non-abelian gauge theory
J. S. Cruz-Filho, R. G. G. Amorim, F. C. Khanna +3
The Seiberg-Witten formalism has been realized as an electrodynamics in phase space (associated to the Dirac equation written in phase space) and this fact is explored here with no…
On Gravitational Casimir Effect and Stefan-Boltzmann Law at Finite Temperature
S. C. Ulhoa, A. F. Santos, T. F. Furtado +1
Gravitons are described by the propagator in Teleparallel gravity in nearly flat space-time. Finite temperature is introduced by using Thermo Field Dynamics formalism. The Gravitat…
Ricci dark energy in bumblebee gravity model
W. D. R. Jesus, A. F. Santos
The Ricci dark energy is a model inspired by the holographic dark energy models with the dark energy density being proportional to Ricci scalar curvature. Here this model is studie…
