Gravity localization on hybrid branes
D. F. S. Veras, W. T. Cruz, R. V. Maluf +1
This work deals with gravity localization on codimension-1 brane worlds engendered by compacton-like kinks, the so-called hybrid branes. In such scenarios, the thin brane behaviour…
Multiresonance modes in sine-Gordon brane models
W. T. Cruz, R. V. Maluf, D. M. Dantas +1
In this work, we study the localization of the vector gauge field in two five-dimensional braneworlds generated by scalar fields coupled to gravity. The sine-Gordon like potentials…
A nonlinear dynamics for the scalar field in Randers spacetime
J. E. G. Silva, R. V. Maluf, C. A. S. Almeida
We investigate the properties of a real scalar field in the Finslerian Randers spacetime, where the local Lorentz violation is driven by a geometrical background vector. We propose…
Quasinormal frequencies of self-dual black holes
Victor Santos, R. V. Maluf, C. A. S. Almeida
One simplified black hole model constructed from a semiclassical analysis of loop quantum gravity (LQG) is called self-dual black hole. This black hole solution depends on a free d…
Radiative corrections in bumblebee electrodynamics
R. V. Maluf, J. E. G. Silva, C. A. S. Almeida
We investigate some quantum features of the bumblebee electrodynamics in flat spacetimes. The bumblebee field is a vector field that leads to a spontaneous Lorentz symmetry breakin…
Superfield Effective Potential for the 2-form field
C. A. S. Almeida, F. S. Gama, R. V. Maluf +2
We develop a theory describing the superfield extension of the 2-form field coupled to usual chiral and real scalar superfield and find the one-loop Kählerian effective potential i…
