White Dwarf Stellar Structure from Effective Polymer Geometry in Loop Quantum Gravity

Edson Otoniel, Jonathan A. Rebouças, M. C. Araújo +1

We construct an effective Tolman Oppenheimer Volkoff system for cold carbon white dwarfs using the areal radius form of a polymer metric sector motivated by loop quantum gravity. T…

Rarita-Schwinger model in Very Special Relativity

M. C. Araújo, J. Furtado, J. G. Lima +1

In this work, we investigate vacuum polarization in the Rarita-Schwinger model within the framework of Very Special Relativity. We examine both massive and massless spin-3/2 fields…

Polymer Black Hole Surrounded by Quintessence

M. C. Araújo, J. G. Lima, C. R. Muniz +1

In this paper, we study the polymer black hole solution surrounded by a quintessence field. The influence of quintessence on the polymer black hole is investigated through its ther…

Lorentz-violating QED inspired superconductivity

A. F. Morais, M. C. Araújo, T. T. Saraiva +1

We studied a Lorentz-violating inspired Ginzburg-Landau model for superconductivity where we considered a CPT-odd contribution given by , also known as the Carroll-Fie…

Bhabha-like scattering in the Rarita-Schwinger model at finite temperature

M. C. Araújo, J. G. Lima, J. Furtado +1

In this paper, we study a Bhabha-like scattering in a massive Rarita-Schwinger model at finite temperature. The analysis is conducted at the tree level and addresses temperature ef…

Electronic states in a bilayer graphene quantum ripple

M. C. Araújo, M. C. Araújo, A. C. A. Ramos +1

In this paper, we investigate the influence of the geometry in the electronic states of a quantum ripple surface. We have considered an electron governed by the spinless stationary…
