Effective Gravity and Homogeneous Solutions
Daniel Müller
Near the singularity, gravity should be modified to an effective theory, in the same sense as with the Euler-Heisenberg electrodynamics. This effective gravity surmounts to higher…
Homogeneous Solutions of Quadratic Gravity
Daniel Müller
It is believed that soon after the Planck time, Einstein's general relativity theory should be corrected to an effective quadratic theory. In this work we present the 3+1 decomposi…
Perturbations of Dark Matter Gravity
M. D. Maia, A. J. S. Capistrano, D. Muller
Until recently the study of the gravitational field of dark matter was primarily concerned with its local effects on the motion of stars in galaxies and galaxy clusters. On the oth…
Geodesic Motion on Closed Spaces: Two Numerical Examples
Daniel Muller
The geodesic structure is very closely related to the trace of the Laplace operator, involved in the calculation of the expectation value of the energy momentum tensor in Universes…
About Starobinsky inflation
Daniel Muller, Sandro D. P. Vitenti
It is believed that soon after the Planck era, space time should have a semi-classical nature. According to this, the escape from General Relativity theory is unavoidable. Two geom…
The power spectrum of the circular noise
Daniel Müller
The circular noise is important in connection to Mach's principle, and also as a possible probe of the Unruh effect. In this letter the power spectrum of the detector following the…
