Induced Chern-Simons-like action in Lorentz-violating massless QED
F. A. Brito, L. S. Grigorio, M. S. Guimaraes +2
In the present work, we study different aspects of Lorentz and CPT symmetry violation in extended massless QED. By following the observation that the 2+1 dimensional Maxwell-Chern-…
Holographic Description of Heavy-Quark Potentials in an Inflationary Braneworld Scenario
Luciano Barosi, Francisco A. Brito, Amilcar R. Queiroz
We study heavy-quark potential in an inflationary braneworld scenario. The scenario we consider is an (Euclidean) inflating braneworld embedded in a static Euclidean $AdS_5…
Noncommutative field gas driven inflation
Luciano Barosi, Francisco A. Brito, Amilcar R. Queiroz
We investigate early time inflationary scenarios in an Universe filled with a dilute noncommutative bosonic gas at high temperature. A noncommutative bosonic gas is a gas composed…
The ambiguity-free four-dimensional Lorentz-breaking Chern-Simons action
F. A. Brito, J. R. Nascimento, E. Passos +1
The four dimensional Lorentz-breaking finite and determined Chern-Simons like action is generated as a one loop perturbative correction via an appropriate Lorentz-breaking coupling…
Lorentz-CPT violation, radiative corrections and finite temperature
F. A. Brito, J. R. Nascimento, E. Passos +1
In this work we investigate the radiatively induced Chern-Simons-like terms in four-dimensions at zero and finite temperature. We use the approach of rationalizing the fermion prop…
Scalar fields, bent branes, and RG flow
D. Bazeia, F. A. Brito, L. Losano
This work deals with braneworld scenarios driven by real scalar fields with standard dynamics. We show how the first-order formalism which exists in the case of four dimensional Mi…
