Massive neutral particles on heterotic string theory
Marco Olivares, J. R. Villanueva
The motion of massive particles in the background of a charged black hole in heterotic string theory, which is characterized by a parameter , is studied in detail in this paper.…
General dissipative coefficient in warm intermediate and logamediate inflation
Ramon Herrera, Marco Olivares, Nelson Videla
We study a general form for the dissipative coefficient in the context of warm intermediate and logamediate inflationary universe models. We analyze the…
Intermediate inflation on the brane and warped DGP models
Ramon Herrera, Marco Olivares, Nelson Videla
Brane and warped Dvali-Gabadadze-Porrati inflationary universe models in the context of intermediate inflation are studied. In both models we consider that the energy density is a…
Geodesic Structure of Lifshitz Black Holes in 2+1 Dimensions
Norman Cruz, Marco Olivares, J. R. Villanueva
We present a study of the geodesic equations of a black hole space-time which is a solution of the three-dimensional NMG theory and is asymptotically Lifshitz with and …
On the Null Trajectories in Conformal Weyl Gravity
J. R. Villanueva, Marco Olivares
In this work we find analytical solutions to the null geodesics around a black hole in the conformal Weyl gravity. Exact expressions for the horizons are found, and they depend on…
Motion of particles on a Lifshitz black hole in 3+1 dimensions
Marco Olivares, Yerko Vásquez, J. R. Villanueva +1
We study the geodesic structure of a Lifshitz black hole in 3+1 spacetime dimensions that is an exact solution to the Einstein-scalar-Maxwell theory. We investigate the motio…
