Robust Wada Boundaries and Entropy Scaling in pp-Wave Spacetimes
Pedro Henrique Barboza Rossetto, Vanessa Carvalho de Andrade, Daniel Müller
We study the dynamics of the geodesics of pp-wave spacetimes with polynomial profiles, which are dynamically equivalent to the motion of a classical particle in a two-dimensional h…

Tilt in quadratic gravity II
Waleska P. F. de Medeiros, Daniel Müller, Oliver F. Piattella +2
We investigate a tilted fluid component on a Bianchi V geometry in the theories of General Relativity (GR) and Quadratic Gravity (QG). The main objective of this work is the study…

Six-dimensional cosmological models with conformal extensions
Daniel Muller, Sergey G. Rubin, Ilya L. Shapiro +1
We consider the background cosmological solutions in the (six-dimensional) model with one time and five space coordinates. The theory of our interest has the action composed b…
