Gödel-type Solutions in Cubic Galileon Gravity

Abstract

We address the homogeneous in space and time (ST-homogeneous) Gödel-type metrics within the cubic galileon theory, a particular class of generalized galileon theories. We check the consistency of such spacetimes for a physically well-motivated matter content, namely, a perfect fluid and an electromagnetic field. In this scenario, we find that the admissible solutions impose constraints on the constant couplings ($c_i$'s) of the cubic galileon theory to ensure the consistency. Also, we show the existence of a vacuum completely causal solution.
