Bianchi type I cosmology with a Kalb-Ramond background field
R. V. Maluf, Juliano C. S. Neves
An effect of the Lorentz symmetry breaking is pointed out in the cosmological context. Using a Bianchi I geometry coupled to the Kalb-Ramond field, a consequence of the Lorentz sym…

Exact solution for a traversable wormhole in a curvature-coupled antisymmetric background field
R. V. Maluf, C. R. Muniz
In this work, we study a traversable wormhole sourced by an ideal matter fluid with an antisymmetric 2-tensor background field coupled to gravity in a scenario of spontaneously bro…

Bumblebee field as a source of cosmological anisotropies
R. V. Maluf, Juliano C. S. Neves
In this work, a bumblebee field is adopted in order to generate cosmological anisotropies. For that purpose, we assume a Bianchi I cosmology, as the background geometry, and a bumb…
