Does Planck mass run on the cosmological horizon scale?
Georg Robbers, Niayesh Afshordi, Michael Doran
Einstein's theory of general relativity, which contains a universal value of the Planck mass, has been so far successfully invoked to explain gravitational dynamics from sub-millim…
Cuscuton Cosmology: Dark Energy meets Modified Gravity
Niayesh Afshordi, Daniel J. H. Chung, Michael Doran +1
In a companion paper (hep-th/0609150), we have introduced a model of scalar field dark energy, Cuscuton, which can be realized as the incompressible (or infinite speed of sound) li…
Impact of three years of data from the Wilkinson Microwave Anisotropy Probe on cosmological models with dynamical dark energy
Michael Doran, Georg Robbers, Christof Wetterich
The first three years of observation of the Wilkinson Microwave Anisotropy Probe (WMAP) have provided the most precise data on the anisotropies of the cosmic microwave background (…
Baryon Acoustic Oscillations and Dynamical Dark Energy
Michael Doran, Steffen Stern, Eduard Thommes
We compute the impact of dark energy at last scattering on measurements of baryon acoustic oscillations (BAOs). We show that an early dark energy component can contribute a systema…
What measurable zero point fluctuations can(not) tell us about dark energy
Michael Doran, Joerg Jaeckel
We show that laboratory experiments cannot measure the absolute value of dark energy. All known experiments rely on electromagnetic interactions. They are thus insensitive to parti…
Early Dark Energy Cosmologies
Michael Doran, Georg Robbers
We propose a novel parameterization of the dark energy density. It is particularly well suited to describe a non-negligible contribution of dark energy at early times and contains…
