Simulations of the End of Supersymmetric Hybrid Inflation and Non-Topological Soliton Formation
Matt Broadhead, John McDonald
We present two- and three-dimensional simulations of the growth of quantum fluctuations of the scalar fields in supersymmetric hybrid inflation models. For a natural range of coupl…

Two-Field Q-ball Solutions of Supersymmetric Hybrid Inflation
Matt Broadhead, John McDonald
We demonstrate the existence of two-field Q-ball solutions of the scalar field equations of supersymmetric D- and F-term hybrid inflation. The solutions consist of a complex inflat…

Growth of Inflaton Perturbations and the Post-Inflation Era in Supersymmetric Hybrid Inflation Models
Matt Broadhead, John McDonald
It has been shown that hybrid inflation may end with the formation of non-topological solitons of inflaton field. As a first step towards a fully realistic picture of the post-infl…
