Configurational entropy of anti-de Sitter black holes
Nelson R. F. Braga, Roldao da Rocha
Recent studies indicate that the configurational entropy is an useful tool to investigate the stability and (or) the relative dominance of states for diverse physical systems. Rece…
Stability of the graviton Bose-Einstein condensate in the brane-world
Roberto Casadio, Roldao da Rocha
We consider a solution of the effective four-dimensional Einstein equations, obtained from the general relativistic Schwarzschild metric through the principle of Minimal Geometric…
New fermions in the bulk
K. P. S. de Brito, Roldao da Rocha
Spinor fields on 5-dimensional Lorentzian manifolds are classified, according to the geometric Fierz identities that involve their bilinear covariants. Based upon this classificati…
Conditional entropy of glueball states
Alex E. Bernardini, Nelson R. F. Braga, Roldao da Rocha
The conditional entropy of glueball states is calculated using a holographic description. Glueball states are represented by a supergravity dual picture, consisting of a 5-dimensio…
The role of singular spinor fields in a torsional gravity, Lorentz-violating, framework
A. F. Ferrari, J. A. S. Neto, R. da Rocha
In this work, we consider a generalization of quantum electrodynamics including Lorentz violation and torsional-gravity, in the context of general spinor fields as classified in th…
Matter localization on brane-worlds generated by deformed defects
Alex E. Bernardini, Roldao da Rocha
Localization and mass spectrum of bosonic and fermionic matter fields of some novel families of asymmetric thick brane configurations generated by deformed defects are investigated…
