The Gravitational Wave Spectrum of Chain Inflation
Katherine Freese, Aliki Litsa, Martin Wolfgang Winkler
Chain inflation is an alternative to slow-roll inflation in which the inflaton tunnels along a large number of consecutive minima in its potential. In this work we perform the firs…
Modified gravity approaches to the cosmological constant problem
The FADE Collaboration, Heliudson Bernardo, Benjamin Bose +5
The cosmological constant and its phenomenology remain among the greatest puzzles in theoretical physics. We review how modifications of Einstein's general relativity could allevia…
Natural Chain Inflation
Katherine Freese, Aliki Litsa, Martin Wolfgang Winkler
In Chain Inflation the universe tunnels along a series of false vacua of ever-decreasing energy. The main goal of this paper is to embed Chain Inflation in high energy fundamental…
Primordial non-Gaussianity from the Effects of the Standard Model Higgs during Reheating after Inflation
Aliki Litsa, Katherine Freese, Evangelos I. Sfakianakis +2
We propose a new way of studying the Higgs potential at extremely high energies. The Standard Model (SM) Higgs boson, as a light spectator field during inflation in the early Unive…
Large Density Perturbations from Reheating to Standard Model particles due to the Dynamics of the Higgs Boson during Inflation
Aliki Litsa, Katherine Freese, Evangelos I. Sfakianakis +2
Cosmic Microwave Background (CMB) observations are used to constrain reheating to Standard Model (SM) particles after a period of inflation. As a light spectator field, the SM Higg…
