How Decoherence Affects the Probability of Slow-Roll Eternal Inflation
Kimberly K. Boddy, Sean M. Carroll, Jason Pollack
Slow-roll inflation can become eternal if the quantum variance of the inflaton field around its slowly rolling classical trajectory is converted into a distribution of classical sp…
Boxes, Boosts, and Energy Duality: Understanding the Galactic-Center Gamma-Ray Excess through Dynamical Dark Matter
Kimberly K. Boddy, Keith R. Dienes, Doojin Kim +3
Many models currently exist which attempt to interpret the excess of gamma rays emanating from the Galactic Center in terms of annihilating or decaying dark matter. These models ty…
Hidden Sector Hydrogen as Dark Matter: Small-scale Structure Formation Predictions and the Importance of Hyperfine Interactions
Kimberly K. Boddy, Manoj Kaplinghat, Anna Kwa +1
We study the atomic physics and the astrophysical implications of a model in which the dark matter is the analog of hydrogen in a secluded sector. The self interactions between dar…
Lines and Boxes: Unmasking Dynamical Dark Matter through Correlations in the MeV Gamma-Ray Spectrum
Kimberly K. Boddy, Keith R. Dienes, Doojin Kim +3
Identifying signatures of dark matter at indirect-detection experiments is generally more challenging for scenarios involving non-minimal dark sectors such as Dynamical Dark Matter…
