Improved Estimates of Cosmological Perturbations
We recently derived exact solutions for the scalar, vector, and tensor mode functions of a single, minimally coupled scalar plus gravity in an arbitrary homogeneous and isotropic background. These solutions are applied to obtain improved estimates for the primordial scalar and tensor power spectra of anisotropies in the cosmic microwave background.

متن کاملString Scale Cosmological Constant
The cosmological constant is an unexplained until now phenomena of nature that requires an explanation through string effects. The apparent discrepancy between theory and experiment is enourmous and has already been explained several times by the author including mechanisms. In this work the string theory theory of abolished string modes is documented and given perturbatively to all loop orders...
متن کاملEstimates of leaf vein density are scale dependent.
Leaf vein density (LVD) has garnered considerable attention of late, with numerous studies linking it to the physiology, ecology, and evolution of land plants. Despite this increased attention, little consideration has been given to the effects of measurement methods on estimation of LVD. Here, we focus on the relationship between measurement methods and estimates of LVD. We examine the depende...
متن کاملDressed Skeleton Expansion and the Coupling Scale Ambiguity Problem*
We present the Dressed Skeleton Expansion (DSE) as a method of perturbative calculation in quantum field theories, without the scale ambiguity problem. We illustrate the application of the DSE method to the two-particle elastic scattering amplitude in 4: theory, and compare this method with the usual perturbative expansion, combined with scale setting prescriptions. Submitted to Physics Letters...
متن کاملQuantum Signature of Cosmological Large Scale Structures
We demonstrate that to all large scale cosmological structures where gravitation is the only overall relevant interaction assembling the system (e.g. galaxies), there is associated a characteristic unit of action per particle whose order of magnitude coincides with the Planck action constant h. This result extends the class of physical systems for which quantum coherence can act on macroscopic ...
