The Energy Density of ”Wound” Fields in a Toroidal Universe

The observational limits on the present energy density of the Universe allow for a component that redshifts like 1/a and can contribute significantly to the total. We show that a possible origin for such a contribution is that the universe has a toroidal topology with ”wound” scalar fields around its cycles.

Density Perturbations in the Universe from Massive Vector Fields

I discuss the possibility of using a massive vector field to generate the density perturbation in the Universe. I find that a scale-invariant superhorizon spectrum of vector field perturbations is possible to generate during inflation. The associated curvature perturbation is imprinted onto the Universe following the curvaton scenario. The mechanism does not generate a long-range anisotropy bec...

Gaussianity of Cosmic Velocity Fields and Linearity of the Velocity – Gravity Relation

We present a numerical study of the relation between the cosmic peculiar velocity field and the gravitational acceleration field. We show that on mildly non-linear scales (4–10 hMpc Gaussian smoothing), the distribution of the Cartesian coordinates of each of these fields is well approximated by a Gaussian. In particular, their kurtoses and negentropies are small compared to those of the veloci...

Characteristic scales of initial density and velocity fields

For the initial fields of the density contrast and peculiar velocity, we theoretically calculate the ‘differential’ and ‘integral’ length scales, i.e., statistical measures that respectively characterize the small-scale zero crossings and large-scale correlation of a random field. The length scales and associated mass scales are related to the length and mass scales observed for (1) halos of yo...

Fractal universe and quantum gravity.

We propose a field theory which lives in fractal spacetime and is argued to be Lorentz invariant, power-counting renormalizable, ultraviolet finite, and causal. The system flows from an ultraviolet fixed point, where spacetime has Hausdorff dimension 2, to an infrared limit coinciding with a standard four-dimensional field theory. Classically, the fractal world where fields live exchanges energ...
