Gödel-type solution in modified gravity
C. J. Ferst, A. F. Santos
In this paper, we will examine the problem of violation of causality in modified gravity, where is the Ricci scalar and is the trace of the energy-momentum tensor…

Gödel solution in the bumblebee gravity
J. R. Nascimento, A. Yu. Petrov, A. F. Santos +1
Here, we consider a gravity theory involving a spontaneous Lorentz symmetry breaking called the bumblebee model. We show that, at certain values of the bumblebee field, the Gödel m…

On Gödel-type Solution in Rastall's Gravity
A. F. Santos, S. C. Ulhoa
Rastall's theory is a generalization of Einstein's equations in which the energy-momentum tensor is not a conserved quantity, its covariant derivative is proportional to the gradie…
