Non-minimal coupling of fermion to the torsion in the modified teleparallel braneworld
A. R. P. Moreira, J. E. G. Silva, C. A. S. Almeida
We study a spin 1/2 fermion in a teleparallel f(T) domain-wall thick braneworld. By assuming a non-minimal coupling of fermion to the torsion, a geometric alternative to the Yukawa…
The bumblebee field excitations in a cosmological braneworld
L. A. Lessa, J. E. G. Silva, C. A. S. Almeida
We investigated the effects of the spacetime curvature and extra dimensions on the excitations of a self-interacting vector field known as the bumblebee field. The self-interacting…
Dirac equation on a catenoid bridge: a supersymmetric approach
Ö. Yeşiltaş, J. Furtado, J. E. G. Silva
In this paper, we study the Dirac equation for an electron constrained to move on a catenoid surface. We decoupled the two components of the spinor and obtained two Klein-Gordon-li…
First-order formalism for thick branes in gravity
A. R. P. Moreira, F. C. E. Lima, J. E. G. Silva +1
In this paper, we study the thick brane scenario constructed in the recently proposed theories of gravity, where is called the torsion scalar, and $\mathcal{…
Teleparallel gravity: Effects of torsion in 6D braneworlds
A. R. P. Moreira, J. E. G. Silva, C. A. S. Almeida
Braneworld models are interesting theoretical and phenomenological frameworks to search for new physics beyond the standard model of particles and cosmology. In this work, we discu…
Position-dependent mass effects on a bilayer graphene catenoid bridge
J. E. G. Silva, J. Furtado, A. C. A. Ramos
We study the electronic properties of a position-dependent effective mass electron on a bilayer graphene catenoid bridge. We propose a position-dependent mass (PDM) as a function o…
