From Non-trivial Geometries to Power Spectra and Vice Versa
D. J. Brooker, N. C. Tsamis, R. P. Woodard
We review a recent formalism which derives the functional forms of the primordial -- tensor and scalar -- power spectra of scalar potential inflationary models. The formalism incor…
Final Thoughts on the Power Spectra of Scalar Potential Models
D. J. Brooker, N. C. Tsamis, R. P. Woodard
We give final shape to a recent formalism for deriving the functional forms of the primordial power spectra of single-scalar potential models and theories which are related to them…
How to Produce an Arbitrarily Small Tensor to Scalar Ratio
Daniel J. Brooker
We construct a toy a model which demonstrates that large field single scalar inflation can produce an arbitrarily small scalar to tensor ratio in the window of e-foldings recoverab…
Role of electron-electron interactions in the charge dynamics of rare-earth-doped CaFe2As2
Zhen Xing, T. J. Huffman, Peng Xu +8
We have investigated the charge dynamics and the nature of many-body interactions in La- and Pr- doped CaFe2As2. From the infrared part of the optical conductivity, we discover tha…
Precision Predictions for the Primordial Power Spectra from f(R) Models of Inflation
D. J. Brooker, S. D. Odintsov, R. P. Woodard
We study the power spectra of f(R) inflation using a new technique in which the norm-squared of the mode functions is evolved. Our technique results in excellent analytic approxima…
The Effect of Features on the Functional Form of the Scalar Power Spectrum
D. J. Brooker, N. C. Tsamis, R. P. Woodard
We study how the scalar power spectrum of single-scalar inflation depends functionally on models with features which have been proposed to explain anomalies in the data. We exploit…
