Just enough inflation: power spectrum modifications at large scales
Michele Cicoli, Sean Downes, Bhaskar Dutta +2
We show that models of `just enough' inflation, where the slow-roll evolution lasted only e-foldings, feature modifications of the CMB power spectrum at large angular scale…
Clearing the Brush: The Last Stand of Solo Small Field Inflation
Joseph Bramante, Sean Downes, Landon Lehman +1
By incorporating both the tensor-to-scalar ratio and the measured value of the spectral index, we set a bound on solo small field inflation of .…
Remarks on Realizing Inflation in String and Particle Physics Models
Sean Downes
The recent measurements of cosmological parameters by the Planck collaboration favors inflationary models with a redshifted spectrum and a very low tensor-to-scalar ratio. Two well…
Cold Rydberg atoms for quantum simulation of exotic condensed matter interactions
J. P. Hague, S. Downes, C. MacCormick +1
Quantum simulators could provide an alternative to numerical simulations for understanding minimal models of condensed matter systems in a controlled way. Typically, cold atom syst…
Power Suppression at Large Scales in String Inflation
Michele Cicoli, Sean Downes, Bhaskar Dutta
We study a possible origin of the anomalous suppression of the power spectrum at large angular scales in the cosmic microwave background within the framework of explicit string inf…
Inflection Points and the Power Spectrum
Sean Downes, Bhaskar Dutta
Inflection point inflation generically includes a deviation from slow-roll when the inflaton approaches the inflection point. Such deviations are shown to be generated by transitio…
