Anisotropic non-Gaussianity from Rotational Symmetry Breaking Excited Initial States
Amjad Ashoorioon, Roberto Casadio, Tomi Koivisto
If the initial quantum state of the primordial perturbations broke rotational invariance, that would be seen as a statistical anisotropy in the angular correlations of the cosmic m…
1/N Resolution to Inflationary eta-Problem
A. Ashoorioon, U. Danielsson, M. M. Sheikh-Jabbari
We observe that the dominant one loop contribution to the graviton propagator in the theory of N (N>>1) light scalar fields ϕ_a (with masses smaller than M_{pl}/\sqrt{N}) minimally…
Running of the Spectral Index and Violation of the Consistency Relation Between Tensor and Scalar Spectra from trans-Planckian Physics
A. Ashoorioon, J. L. Hovdebo, R. B. Mann
One of the firm predictions of inflationary cosmology is the consistency relation between scalar and tensor spectra. It has been argued that such a relation -if experimentally conf…
