Properties of an axisymmetric Lorentzian non-commutative black hole
A. A. Araújo Filho, J. R. Nascimento, A. Yu. Petrov +2
In this work, we start by examining a spherically symmetric black hole within the framework of non-commutative geometry and apply a modified Newman-Janis method to obtain a new rot…
Landau levels for massive disclinated graphene-based topological insulator
G. Q. Garcia, J. R. S. Oliveira, P. J. Porfírio +1
In this work, we investigate the massive Kane-Mele model for graphene in the presence of disclination and an external magnetic field, where graphene behaviors as a topological insu…
Gödel-type solutions within the gravity
J. R. Nascimento, A. Yu. Petrov, P. J. Porfirio +1
In this work, we scrutinize the consistency of spacetime homogeneous Gödel-type metrics within theories of gravity for well-motivated matter sources. As it is well known…
On the causality aspects of the dynamical Chern-Simons modified gravity
P. J. Porfirio, J. B. Fonseca-Neto, J. R. Nascimento +1
We discuss the Gödel-type solutions within the dynamical Chern-Simons modified gravity in four dimensions. Within our study, we show that in the vacuum case the causal solutions ar…
