The Higgs field and early universe cosmology: a (brief) review
Bart Horn
We review and discuss recent work exploring the implications of the Higgs field for early universe cosmology, and vice versa. Depending on the model under consideration the Higgs m…
Observable relics of the simple harmonic universe
Peter Gilmartin, Bart Horn
We analyze observational signatures arising from an epoch in cosmology corresponding to the simple harmonic universe, which consists of positive curvature, a negative cosmological…
Double-soft graviton amplitudes and the extended BMS charge algebra
Jacques Distler, Raphael Flauger, Bart Horn
We discuss how scattering amplitudes in 4d Minkowski spacetime which involve multiple soft gravitons realize the algebra of BMS charges on the null boundary. In particular, we show…
Trapped Inflation
Daniel Green, Bart Horn, Leonardo Senatore +1
We analyze a distinctive mechanism for inflation in which particle production slows down a scalar field on a steep potential, and show how it descends from angular moduli in string…
